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:

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:

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:

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.
