This function is an internal view function that returns the data associated with the current message. It does this by accessing the msg.data variable, which is a built-in variable that stores the data associated with the current message. The function returns the data as a bytes memory type. (autogenerated documentation)

This function is an internal view function that returns the address of the sender of the current message. It works by using the built-in msg.sender variable, which stores the address of the sender of the current message. This function allows the contract to access the address of the sender of the current message without having to pass it in as an argument. (autogenerated documentation)

This function is used to transfer ownership of a contract from one address to another. It requires that the new owner address is not the zero address, and then emits an OwnershipTransferred event with the old and new owner addresses. Finally, it sets the _owner variable to the new owner address. (autogenerated documentation)

This function adds two uint256 values together and returns the result. It uses a require statement to ensure that the result of the addition does not exceed the maximum value of a uint256. If the addition does exceed the maximum value, an error is thrown. (autogenerated documentation)

This function allows an owner to approve a spender to transfer a certain amount of tokens from the owner's account to another account. The owner calls the approve function, passing in the spender's address and the amount of tokens to be transferred. The approve function then emits an Approval event, which is logged on the blockchain. The spender can then call the transferFrom function, passing in the owner's address, the recipient's address, and the amount of tokens to be transferred. The transferFrom function then emits a Transfer event, which is logged on the blockchain. (autogenerated documentation)

The approve() function allows an owner of a token to approve a spender to transfer a certain amount of tokens from the owner's account. This is done by setting an allowance for the spender, which is stored in the contract. The spender can then use the transferFrom() function to transfer the approved amount of tokens from the owner's account to the recipient's account. The Transfer and Approval events are triggered when the transfer is successful. (autogenerated documentation)

balanceOf: This function returns the balance of a given account. It takes an address as an argument and returns the balance of that account as a uint256.transfer: This function transfers a given amount of tokens from the sender to the recipient. It takes two arguments, the recipient address and the amount of tokens to be transferred, and returns a boolean indicating whether the transfer was successful or not.allowance: This function returns the amount of tokens that a spender is allowed to spend from the owner's account. It takes two arguments, the owner's address and the spender's address, and returns the amount of tokens that the spender is allowed to spend from the owner's account as a uint256.

This function is used to retrieve the address of the token contract associated with the distribution contract. It works by returning the address of the token contract stored in the distTokens variable. (autogenerated documentation)

This function is an internal pure function that calculates the modulo of two unsigned 256-bit integers (a and b). It returns the remainder of the division of a by b. It also includes an error message that is triggered if b is equal to zero. (autogenerated documentation)

This function is an internal pure function that calculates the modulo of two uint256 numbers, a and b. It requires that b is not equal to 0, and if it is, it will throw an error with the message provided in the errorMessage parameter. If b is not equal to 0, the function will return the modulo of a and b. (autogenerated documentation)

This function is an internal function that performs multiplication of two uint256 values. It first checks if the first value is 0, and if so, it returns 0. Otherwise, it multiplies the two values and checks if the result is valid by dividing the result by the first value and comparing it to the second value. If the result is valid, it returns the result, otherwise it throws an error. (autogenerated documentation)

name() is a function that returns the name of the token as a string. It is an external view function, meaning that it does not modify the state of the contract and does not require any gas to be executed. It simply returns the name of the token stored in the contract. getOwner() is a function that returns the address of the owner of the token. It is an external view function, meaning that it does not modify the state of the contract and does not require any gas to be executed. It simply returns the address of the owner stored in the contract. balanceOf() is a function that returns the balance of a given account. It is an external view function, meaning that it does not (autogenerated documentation)

This function returns the address of the owner of the contract. It works by returning the value stored in the _owner variable, which is set when the contract is deployed. (autogenerated documentation)

This function allows the owner of a contract to renounce their ownership of the contract. It emits an OwnershipTransferred event, which notifies any listeners that the ownership of the contract has been transferred from the current owner to address 0 (which is the address of a null account). The _owner variable is then set to address 0, indicating that the contract no longer has an owner. (autogenerated documentation)

This function sends a specified amount of tokens to an array of addresses. It takes two parameters, an array of addresses and a uint256 value. It then loops through the array of addresses and sends the specified amount of tokens to each address. The amount is multiplied by 10 to the power of the token's decimal value to ensure the correct amount is sent. Finally, the function returns a boolean value indicating whether the transfer was successful. (autogenerated documentation)

This function sets the address of the token contract and the token decimal for the contract. It is only accessible to the owner of the contract. The address of the token contract is stored in the distTokens variable and the token decimal is stored in the decimal variable. The token variable is set to an instance of the IBEP20 contract using the address stored in distTokens. (autogenerated documentation)

This function is an internal pure function that subtracts two uint256 values and returns the result. It uses a "SafeMath" library to check for overflow and throws an error if an overflow occurs. The function takes two uint256 values as parameters and subtracts them, returning the result. (autogenerated documentation)

This function is an internal pure function that subtracts two uint256 values and returns the result. It requires that the second value (b) is less than or equal to the first value (a). If this condition is not met, an error message is thrown. The function then subtracts the two values and returns the result. (autogenerated documentation)

It works by accessing (autogenerated documentation)

transfer() is a function that allows users to transfer tokens from one address to another. It takes two parameters, the recipient address and the amount of tokens to be transferred. The function checks if the sender has enough tokens to transfer and if so, it subtracts the amount from the sender's balance and adds it to the recipient's balance. It then emits a Transfer event to notify the network of the transfer.Briefly describe what this function does and how it works.allowance() is a function that allows users to check the amount of tokens that have been approved for a spender to transfer from a particular address. It takes two parameters, the owner address and the spender address. The function returns the amount (autogenerated documentation)

This function allows users to transfer tokens from one address to another. It takes three parameters: the address of the sender, the address of the recipient, and the amount of tokens to be transferred. The function returns a boolean value indicating whether the transfer was successful or not. Additionally, two events are triggered: Transfer and Approval. The Transfer event is triggered when the transfer is successful and contains the addresses of the sender and recipient, as well as the amount of tokens transferred. The Approval event is triggered when the transfer is approved and contains the address of the owner, the address of the spender, and the amount of tokens approved. (autogenerated documentation)

This function allows the current owner of a contract to transfer ownership to a new address. It can only be called by the current owner and requires the new owner's address as an argument. Once called, the function will update the contract's owner address to the new address. (autogenerated documentation)
