firestring_set_error_handler(3) Library Functions Manual firestring_set_error_handler(3)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 when-
ever 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 sim-
ply 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

gnutls_global_set_mem_functions - set the memory allocation functions
SYNOPSIS
#include <gnutls/gnutls.h>
void gnutls_global_set_mem_functions(gnutls_alloc_function alloc_func, gnutls_alloc_function secure_alloc_func, gnutls_is_secure_function
is_secure_func, gnutls_realloc_function realloc_func, gnutls_free_function free_func);
ARGUMENTS
gnutls_alloc_function alloc_func
it's the default memory allocation function. Like malloc().
gnutls_alloc_function secure_alloc_func
This is the memory allocation function that will be used for sensitive data.
gnutls_is_secure_function is_secure_func
a function that returns 0 if the memory given is not secure. May be NULL.
gnutls_realloc_function realloc_func
A realloc function
gnutls_free_function free_func
The function that frees allocated data. Must accept a NULL pointer.
DESCRIPTION
This is the function were you set the memory allocation functions gnutls is going to use. By default the libc's allocation functions (mal-
loc(), free()), are used by gnutls, to allocate both sensitive and not sensitive data. This function is provided to set the memory alloca-
tion functions to something other than the defaults (ie the gcrypt allocation functions).
This function must be called before gnutls_global_init() is called. This function is not thread safe.
