int sqFTruncate(filenum, fileoffset)
Parms:
filenum file number
fileoffset file byte offset to truncate to.
return: 0 if ok. non-zero to fail the primitive call.
From: Interpreter, file plugin
Why:
To truncate the file, this removes bytes from the end, or extends the file depending on the meaning of truncate in the file system.
Responsibility:
By default it is defined as
#define sqFTruncate(filenum, fileoffset) true
MacIntosh
os-9/OSXCarbon
#define sqFTruncate(f,o) ftruncate(fileno(f), o)
Cocoa:
See iPhone
iPhone
#define sqFTruncate(f,o) ftruncate(fileno(f), o)
Unix
#define sqFTruncate(f,o) ftruncate(fileno(f), o)
Windows
??? It's unclear I think it inherits the #define sqFTruncate(filenum, fileoffset) true
BUGS
Does Windows support sqFTruncate???
