explain_popen_or_die - process I/O and report errorsSYNOPSIS
#include <libexplain/popen.h>FILE *explain_popen_or_die(const char *command, const char *flags);
DESCRIPTION
The explain_popen_or_die function is used to call the popen(3) system call. On failure an explanation will be printed to stderr, obtained from explain_popen(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:
FILE *fp = explain_popen_or_die(command, flags);
- command
- The command, exactly as to be passed to the popen(3) system call.
- flags
- The flags, exactly as to be passed to the popen(3) system call.
- Returns:
- This function only returns on success, see popen(3) for more information. On failure, prints an explanation and exits.
