<a name="DESCRIPTION"></a><h2 class="nroffsh">DESCRIPTION</h2>
<p class="level0">This function works exactly as <a Class="emphasis" href="./curl_global_init.html">curl_global_init</a> with one addition: it allows the application to set callbacks to replace the otherwise used internal memory functions.
<p class="level0">If you are using libcurl from multiple threads or libcurl was built with the threaded resolver option then the callback functions must be thread safe. The threaded resolver is a common build option to enable (and in some cases the default) so we strongly urge you to make your callback functions thread safe.
<p class="level0">All callback arguments must be set to valid function pointers. The prototypes for the given callbacks must match these:
<p class="level0"><a name="void"></a><span class="nroffip">void *malloc_callback(size_t size);</span>
<p class="level1">To replace malloc()
<p class="level0"><a name="void"></a><span class="nroffip">void free_callback(void *ptr);</span>
<p class="level1">To replace free()
<p class="level0"><a name="void"></a><span class="nroffip">void *realloc_callback(void *ptr, size_t size);</span>
<p class="level1">To replace realloc()
<p class="level0"><a name="char"></a><span class="nroffip">char *strdup_callback(const char *str);</span>
<p class="level1">To replace strdup()
<p class="level0"><a name="void"></a><span class="nroffip">void *calloc_callback(size_t nmemb, size_t size);</span>
<p class="level1">To replace calloc()
<p class="level0">This function is otherwise the same as <a Class="emphasis" href="./curl_global_init.html">curl_global_init</a>, please refer to that man page for documentation. <a name="CAUTION"></a><h2 class="nroffsh">CAUTION</h2>
<p class="level0">Manipulating these gives considerable powers to the application to severely screw things up for libcurl. Take care! <a name="SEE"></a><h2 class="nroffsh">SEE ALSO</h2>
