explain_fcntl_or_die(3)	   Library Functions Manual    explain_fcntl_or_die(3)

NAME
       explain_fcntl_or_die - manipulate a file	descriptor and report errors

SYNOPSIS
       #include	<libexplain/fcntl.h>
       int explain_fcntl_or_die(int fildes, int	command, long arg);

DESCRIPTION
       The  explain_fcntl_or_die  function is used to call the fcntl(2)	system
       call.  On failure an explanation	will be	printed	 to  stderr,  obtained
       from  explain_fcntl(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:
	      int result = explain_fcntl_or_die(fildes,	command, arg);

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

       command The command, exactly as to be passed  to	 the  fcntl(2)	system
	       call.

       arg     The arg,	exactly	as to be passed	to the fcntl(2)	system call.

       Returns:
	       This  function only returns on success, and it returns whatever
	       was returned by the fcntl(2) call; depending  on	 the  command,
	       this  may  have	no use.	 On failure, prints an explanation and
	       exits, it does not return.
