explain_realloc_or_die(3) Library Functions Manual explain_realloc_or_die(3)
NAME
explain_realloc_or_die - Allocate and free dynamic memory and report errors
SYNOPSIS
#include <libexplain/realloc.h>
void explain_realloc_or_die(void *ptr, size_t size);
DESCRIPTION
The explain_realloc_or_die function is used to call the realloc(3) system call. On failure an explanation will be printed to stderr,
obtained from explain_realloc(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:
void *new_ptr = explain_realloc_or_die(ptr, size);
ptr The ptr, exactly as to be passed to the realloc(3) system call.
size The size, exactly as to be passed to the realloc(3) system call.
Returns:
This function only returns on success. On failure, prints an explanation and exits.
