NAME
       explain_truncate_or_die - truncate a file and report errors

SYNOPSIS
       #include <libexplain/truncate.h>
       void explain_truncate_or_die(const char *pathname, long long length);

DESCRIPTION
       The  explain_truncate_or_die  function  is  used to call the truncate(2) system call.  On failure an explanation will be printed to stderr,
       obtained from explain_truncate(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_truncate_or_die(pathname, length);

       pathname
	       The pathname, exactly as to be passed to the truncate(2) system call.

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

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

SEE ALSO

	       truncate a file to a specified length

       explain_truncate(3)
