FWrite3 Function

Write the contents of a buffer to an open file.

Namespace:  XSharp.RT
Assembly:  XSharp.RT (in XSharp.RT.dll) Version: 2.3b
Syntax
Copy
 FUNCTION FWrite3(
	ptrHandle AS IntPtr,
	ptrBuffer AS IntPtr,
	dwBytes AS DWORD
) AS DWORD
View Source

Parameters

ptrHandle
Type: IntPtr
The handle of the file to write to.
ptrBuffer
Type: IntPtr
A pointer to the buffer to write.
dwBytes
Type: UInt32
The number of bytes in <ptrBuffer> to write, beginning at the current file pointer position.

Return Value

Type: UInt32
The number of bytes written.
If the value returned is equal to <dwBytes>, the operation was successful.
If the return value is less than <dwBytes> or 0, this means that the length of <ptrBuffer> is less than <dwBytes>, or the disk is full, or another error has occurred.  FError() can be used to determine the specific error.
Remarks
FWrite3() is a strongly-typed version of FWrite().  Moreover, the second argument in FWrite3() is a pointer to a buffer, instead of a string.  See FWrite() for details.
Remarks
Tip Tip
This function is included for compatibility. We do not recomment using static memory for file i/o operations. We recommend that you use the function overload that takes a byte array parameter in stead.
Examples
This example writes the contents of a PSZ to a file:.
X#
Copy
1LOCAL pszBuff AS PSZ
2LOCAL ptrHandle AS PTR
3pszBuff := "hello" // psz converted data
4ptrHandle := FOpen2("temp.bin", FO_READWRITE)
5IF ptrHandle != F_ERROR
6    FWrite3(ptrHandle, pszBuff, PszLen(pszBuff)
7ENDIF
