explain_truncate_or_die(3) Library Functions Manual explain_truncate_or_die(3)

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,  ob-
       tained  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  fol-
       lowing 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.
