explain_fread_or_die - binary stream input and report errors SYNOPSIS
#include <libexplain/fread.h> void explain_fread_or_die(void *ptr, size_t size, size_t nmemb, FILE *fp); DESCRIPTION
The explain_fread_or_die function is used to call the fread(3) system call. On failure an explanation will be printed to stderr, obtained from explain_fread(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: size_t how_many = explain_fread_or_die(ptr, size, nmemb, fp); ptr The ptr, exactly as to be passed to the fread(3) system call. size The size, exactly as to be passed to the fread(3) system call. nmemb The nmemb, exactly as to be passed to the fread(3) system call. fp The fp, exactly as to be passed to the fread(3) system call. Returns: This function only returns on success, the number read or 0 on end-of-input. On failure, prints an explanation and exits. SEE ALSO

explain_fwrite_or_die - binary stream output and report errors SYNOPSIS
#include <libexplain/fwrite.h> size_t explain_fwrite_or_die(const void *ptr, size_t size, size_t nmemb, FILE *fp); DESCRIPTION
The explain_fwrite_or_die function is used to call the fwrite(3) system call. On failure an explanation will be printed to stderr, obtained from explain_fwrite(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: size_t result = explain_fwrite_or_die(ptr, size, nmemb, fp); ptr The ptr, exactly as to be passed to the fwrite(3) system call. size The size, exactly as to be passed to the fwrite(3) system call. nmemb The nmemb, exactly as to be passed to the fwrite(3) system call. fp The fp, exactly as to be passed to the fwrite(3) system call. Returns: This function only returns on success. On failure, prints an explanation and exits. SEE ALSO
