explain_fgets_or_die - input of strings and report errors
#include <libexplain/fgets.h> char *explain_fgets_or_die(char *data, int data_size, FILE *fp);
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.
