explain_setbuf_or_die(3)				     Library Functions Manual					  explain_setbuf_or_die(3)

NAME

       explain_setbuf_or_die - set stream buffer and report errors

SYNOPSIS

       #include <libexplain/setbuf.h>
       void explain_setbuf_or_die(FILE *fp, char *data);
       void explain_setbuf_on_error(FILE *fp, char *data);

DESCRIPTION

       The explain_setbuf_or_die function is used to call the setbuf(3) system call. On failure an explanation will be printed to stderr, obtained
       from the explain_setbuf(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

       The explain_setbuf_on_error function is used to call the setbuf(3) system call. On failure  an  explanation  will  be  printed  to  stderr,
       obtained from the explain_setbuf(3) function, but still returns to the caller.

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

       data    The data, exactly as to be passed to the setbuf(3) system call.

RETURN VALUE

       The  explain_setbuf_or_die  function  only  returns  on	success, see setbuf(3) for more information. On failure, prints an explanation and
       exits, it does not return.

       The explain_setbuf_on_error function always returns the value return by the wrapped setbuf(3) system call.

EXAMPLE

       The explain_setbuf_or_die function is intended to be used in a fashion similar to the following example:
	      explain_setbuf_or_die(fp, data);

SEE ALSO

       setbuf(3)
	       set stream buffer

       explain_setbuf(3)
	       explain setbuf(3) errors

       exit(2) terminate the calling process

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.

SEE ALSO

       pclose(3)
	       process I/O

       explain_pclose(3)
	       explain pclose(3) errors

       exit(2) terminate the calling process
