FWriteLine3 Function | |
Write a string, a carriage-return character, and a linefeed character to an open file, specifying two strongly-typed arguments.
Namespace:
XSharp.Core
Assembly:
XSharp.Core (in XSharp.Core.dll) Version: 2.19
Syntax FUNCTION FWriteLine3(
ptrHandle AS IntPtr,
cBuffer AS STRING,
dwBytes AS DWORD
) AS DWORD
public static uint FWriteLine3(
IntPtr ptrHandle,
string cBuffer,
uint dwBytes
)
Request Example
View SourceParameters
- ptrHandle
- Type: IntPtr
The handle of the file to write to. - cBuffer
- Type: String
The string to write. - dwBytes
- Type: DWord
The number of bytes in cBuffer to write, beginning at the current file pointer position.
Return Value
Type:
DWord
The number of bytes written.
If the value returned is equal to
dwBytes + 2, the operation was successful.
If the return value is less than
dwBytes + 2 or 0, this means that the length of
cBuffer was less than
dwBytes, or the disk is full, or another error has occurred.
Remarks
This function is assumed to handle raw binary data and is not dependent upon the status of SetAnsi(). FWriteText() and FWrite4(), on the other hand, are dependent upon SetAnsi().
Examples
This example uses FWriteLine3() to write 5 bytes. The carriage-return/linefeed pair increase the return value by 2:
1hF := FOpen2("c:\data\sales", FO_READWRITE)
2IF hF != F_ERROR
3 ? FWriteLine3(hF, "Line1", 5)
4ENDIF
