Result = WriteData(#File, *MemoryBuffer, Length)Description
Write the content of the specified memory buffer to a file.
#File The file to write to. *MemoryBuffer The memory address of the data to write to the file. Length The number of bytes to write to the file.
Returns the number of bytes actually written to the file. If there is an error, the return-value is zero.
Because of file buffering, this function may return successful even if there is not enough space left on the output device for the write operation. The file must be opened using a write-capable function (i.e. not with ReadFile()).
*MemoryID = AllocateMemory(1000) ; allocating a memory block If *MemoryID PokeS(*MemoryID, "Store this string in the memory area") ; we write a string into the memory block EndIf If CreateFile(0, "Text.txt") ; we create a new text file... WriteData(0, *MemoryID, 10) ; write the first 10 chars from the memory block into the file CloseFile(0) ; close the previously opened file and so store the written data Else Debug "may not create the file!" EndIf
