NAME
SetFileSize -- Sets the size of a file (V36)
SYNOPSIS
newsize = SetFileSize(fh, offset, mode)
D0 D1 D2 D3
LONG SetFileSize(BPTR, LONG, LONG)FUNCTION
Changes the file size, truncating or extending as needed. Not all handlers may support this; be careful and check the return code. If the file is extended, no values should be assumed for the new bytes. If the new position would be before the filehandle's current position in the file, the filehandle will end with a position at the end-of-file. If there are other filehandles open onto the file, the new size will not leave any filehandle pointing past the end-of-file. You can check for this by looking at the new size.
Do NOT count on any specific values to be in the extended area.
INPUTS
fh - File to be truncated/extended. offset - Offset from position determined by mode. mode - One of OFFSET_BEGINNING, OFFSET_CURRENT, or OFFSET_END.
RESULT newsize - position of new end-of-file or -1 for error.
