and they'd never ever put the ___internal junk in the same file, that would be far too easy.
But if I had to guess, it's a way to get at your program's internal symbols in a way a mere shared library wouldn't be able to. Adding a callback to fork() can't have been easy.
i want to replace the *alloc and free function calls in an existing project with my own functions, to be able to log the adresses etc in a text file. (memoryleak debugging)
I think LD_PRELOAD is what i am looking for.
That way i could create a Library with my own malloc functions and link them... (1 Reply)

Apart from writing debug and statements in constructors is there any way by which we can trace the function call stack at any depth?

I created multiple POSIX threads (on readhat Linux) in a C program in my app. What I am doing is - I am creating threads equal to the number of CPUs in the system and and equal number of instances of a certain data structure, basically a queue implementation.

Hi,
I am new to posix threads. The no of threads to be created depends on the runtime. If I get the number of threads,
I need to forward declare

curl_multi_add_handle
curl_multi_add_handle(3) libcurl Manual curl_multi_add_handle(3)NAME
curl_multi_add_handle - add an easy handle to a multi session
SYNOPSIS
#include <curl/curl.h>
CURLMcode curl_multi_add_handle(CURLM *multi_handle, CURL *easy_handle);
DESCRIPTION
Adds a standard easy handle to the multi stack. This function call will make this multi_handle control the specified easy_handle. Further-
more, libcurl now initiates the connection associated with the specified easy_handle.
When an easy handle has been added to a multi stack, you can not and you must not use curl_easy_perform(3) on that handle!
If the easy handle is not set to use a shared (CURLOPT_SHARE) or global DNS cache (CURLOPT_DNS_USE_GLOBAL_CACHE), it will be made to use
the DNS cache that is shared between all easy handles within the multi handle when curl_multi_add_handle(3) is called.
The easy handle will remain added until you remove it again with curl_multi_remove_handle(3). You should remove the easy handle from the
multi stack before you terminate first the easy handle and then the multi handle:
1 - curl_multi_remove_handle(3)
2 - curl_easy_cleanup(3)
3 - curl_multi_cleanup(3)RETURN VALUE
CURLMcode type, general libcurl multi interface error code.
