SYNOPSIS
#include <firestring.h>-lfirestring
void firestring_set_error_handler(void (*e)())
DESCRIPTION
firestring_set_error_handler() takes the name of a function that takes no parameters and returns void. This function will be called whenever firestring fails to allocate memory.As memory allocation failures are fatal to most programs, firestring does not return errors when functions fail to allocate memory; it simply calls this function, which it expects to call exit() or abort() or in some way terminate execution of the program. It probably is not safe to pass a function that returns, unless you have a framework in place for passing the allocation failure information back to the code calling the firestring function.
The default function calls perror() and then exit().
