When you use this function, all callback arguments must be set to valid function pointers. <p class="level0">The prototypes for the given callbacks should 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() <a name="CAUTION"></a><h2 class="nroffsh">CAUTION</h2><p class="level0">Manipulating these gives considerable powers to the application to severly screw things up for libcurl.
