) -> c_int
Expand description

Get a memory from the pool.

This function never blocks. If no buffers are available in the pool, this function either returns -EAGAIN or allocates a new memory, depending on the pool grow_policy parameter. If the allocation of new memory fails, the function returns -ENOMEM.

@param pool: The memory pool. @param ret_obj: [out] Pointer to the memory.

@return 0 on success, negative errno on error.
