Description
The function httplib_malloc() tries to allocate a block of memory from the heap 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 httplib_set_alloc_callback_func() 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.
Due to the allocation of extra data space for tracking the memory allocation, the LibHTTP memory management functions including the httplib_malloc() function are incompatible with the memory allocation functions provided by the platform. 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.
