 ### Description
 
-The function `httplib_calloc()` tries to allocate a block of memory from the heap for an array elements with a specified size. If this succeeds, the function returns a pointer to the new block. Otherwise the value `NULL` is returned. If a callback function has been registered with the [`set_alloc_callback_func()`](set_alloc_callback_func.md) function, this function will be called to signal to the main application that a block of memory has been allocated. If a callback function has been registered and the allocation of memory fails, the value **0** is passed as the `current_bytes` parameter.

Memory allocated with one set of functions can not be reallocated or freed by the others. Memory corruption or crashes may occur in that case.
