Get pointer to the first vacant block in slab.

Gives pointer to the first vacant memory block in the slab.

Parameters

data_fifo	Pointer to the data_fifo structure.
data	Double pointer to the memory area. If this function returns with success, the caller is now able to write to this memory block. The write operation must not exceed the block size max given to DATA_FIFO_DEFINE.
timeout	Non-negative waiting period to wait for operation to complete (in milliseconds). Use K_NO_WAIT to return without waiting, or K_FOREVER to wait as long as necessary.
