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_SUCCESS, 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.
