Returns

On success, zero is returned. On error, -1 is returned and Stdlib.GetLastError returns the translated error.

Usage

The ftruncate() system call succeeds unless:

Error	Details
Errno.EBADF	The fd argument is not a valid descriptor.
Errno.EINVAL	The fd argument references a socket, not a file.
Errno.EINVAL	The fd descriptor is not open for writing.

[Edit]

Remarks

The truncate() system call causes the file named by path or referenced by fd to be truncated or extended to length bytes in size. If the file was larger than this size, the extra data is lost. If the file was smaller than this size, it will be extended as if by writing bytes with the value zero. With ftruncate(), the file must be open for writing. [Edit]
