explain_ftruncate_or_die(3)				     Library Functions Manual				       explain_ftruncate_or_die(3)

NAME

       explain_ftruncate_or_die - truncate a file and report errors

SYNOPSIS

       #include <libexplain/ftruncate.h>
       void explain_ftruncate_or_die(int fildes, long long length);

DESCRIPTION

       The  explain_ftruncate_or_die  function is used to call the ftruncate(2) system call.  On failure an explanation will be printed to stderr,
       obtained from explain_ftruncate(3), and then the process terminates by calling exit(EXIT_FAILURE).

       This function is intended to be used in a fashion similar to the following example:
	      explain_ftruncate_or_die(fildes, length);

       fildes  The fildes, exactly as to be passed to the ftruncate(2) system call.

       length  The length, exactly as to be passed to the ftruncate(2) system call.

       Returns:
	       This function only returns on success.  On failure, prints an explanation and exits.

SEE ALSO

       ftruncate(2)
	       truncate a file to a specified length

       explain_ftruncate(3)
	       explain ftruncate(2) errors
