NAME¶
explain_fgets_or_die - input of strings and report errors
SYNOPSIS¶
#include <libexplain/fgets.h>
char *explain_fgets_or_die(char *data, int data_size, FILE *fp);
DESCRIPTION¶
The
explain_fgets_or_die function is used to call the
fgets(3)
system call. On failure an explanation will be printed to
stderr,
obtained from
explain_fgets(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_fgets_or_die(data, data_size, fp);
- data
- The data, exactly as to be passed to the fgets(3)
system call.
- data_size
- The data_size, exactly as to be passed to the
fgets(3) system call.
- fp
- The fp, exactly as to be passed to the fgets(3)
system call.
- Returns:
- This function only returns on success; data when a line is
read, or NULL on end‐of‐file. On failure, prints an
explanation and exits.
