firestring_set_error_handler(3)             DragonFly Library Functions Manual

NAME
       firestring_set_error_handler - set the function to be called on an
       allocation failure

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().

RETURN VALUE
       None
