explain_pclose_or_die(3)				     Library Functions Manual					  explain_pclose_or_die(3)

NAME
       explain_pclose_or_die - process I/O and report errors

SYNOPSIS
       #include <libexplain/pclose.h>
       int explain_pclose_or_die(FILE *fp);
       int explain_pclose_success(FILE *fp);
       void explain_pclose_success_or_die(FILE *fp);

DESCRIPTION
       These functions may be used to wait for program termination, and then reprt errors returned by the pclose(3) system call.

   explain_pclose_or_die
       int explain_pclose_or_die(FILE *fp);

       The  explain_pclose_or_die  function  is  used  to  call  the  pclose(3) system call.  On failure an explanation will be printed to stderr,
       obtained from explain_pclose(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:
	      int status = explain_pclose_or_die(fp);

       fp      The fp, exactly as to be passed to the pclose(3) system call.

       Returns:
	       This function only returns on success, see pclose(3) for more information.  On failure, prints an explanation and exits.

   explain_pclose_success_or_die
       void explain_pclose_success_or_die(FILE *);

       The explain_pclose_success_or_die function is used to call the pclose(3) system call.  On failure, including any  exit  status  other  than
       EXIT_SUCCESS,  an  explanation  will  be  printed  to  stderr,  obtained from explain_pclose(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_pclose_success_or_die(fp);

       fp      The fp, exactly as to be passed to the pclose(3) system call.

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

   explain_pclose_success
       int explain_pclose_success(FILE *fp);

       The explain_pclose_success function is used to call the pclose(3) system call.  On failure, including any exit status other than  EXIT_SUC-
       CESS,  an explanation will be printed to stderr, obtained from explain_pclose(3).  However, the priniting of an error message does not also
       cause exit(2) to be called.

       This function is intended to be used in a fashion similar to the following example:
	      int status = explain_pclose_success(command);

       fp      The fp, exactly as to be passed to the pclose(3) system call.

       Returns:
	       the value returned by the pclose(3) system call.  In all cases other than EXIT_SUCCESS,	an  error  message  will  also	have  been
	       printed to stderr.
