NAME¶
explain_fdopen_or_die - stream open functions and report errors
SYNOPSIS¶
#include <libexplain/fdopen.h>
void explain_fdopen_or_die(int fd, const char *mode);
DESCRIPTION¶
The
explain_fdopen_or_die function is used to call the
fdopen(3)
system call. On failure an explanation will be printed to
stderr,
obtained from
explain_fdopen(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_fdopen_or_die(fd, mode);
- fd
- The fd, exactly as to be passed to the fdopen(3)
system call.
- mode
- The mode, exactly as to be passed to the fdopen(3)
system call.
- Returns:
- This function only returns on success. On failure, prints
an explanation and exits.
