NAME

explain_realloc_or_die - Allocate and free dynamic memory and report errors

SYNOPSIS

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.
