Function openthread_sys::otPlatCAlloc

pub unsafe extern "C" fn otPlatCAlloc(
    aNum: size_t, 
    aSize: size_t
) -> *mut c_void

Dynamically allocates new memory. On platforms that support it, should just redirect to calloc. For those that don't support calloc, should support the same functionality:

"The calloc() function contiguously allocates enough space for count objects that are size bytes of memory each and returns a pointer to the allocated memory. The allocated memory is filled with bytes of value zero."

This function is available and can ONLY be used only when support for multiple OpenThread instances is enabled.

@param[in] aNum The number of blocks to allocate @param[in] aSize The size of each block to allocate

@retval void* The pointer to the front of the memory allocated @retval NULL Failed to allocate the memory requested.
