NAME¶
explain_ferror_or_die - check stream status and report errors
SYNOPSIS¶
#include <libexplain/ferror.h>
void explain_ferror_or_die(FILE *fp);
DESCRIPTION¶
The
explain_ferror_or_die function is used to call the
ferror(3)
system call. On failure an explanation will be printed to
stderr,
obtained from
explain_ferror(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_ferror_or_die(fp);
It is essential that this function cal be placed as close as possible to the I/O
code that has caused the problem, otherwise intervening code could have
altered the
errno global variable.
- fp
- The fp, exactly as to be passed to the ferror(3)
system call.
- Returns:
- This function only returns on success. On failure, prints
an explanation and exits.
