I am not sure about SRS for learning API of a language. However I have recently started to use mind maps for that. Whenever I come across a new language or library I take an A4 and a pen and put down all basic concepts. It helps to grasp the big picture of the system and to see the interconnections of different blocks of code. I prefer mind maps to the standard linear up-down way of writing stuff down because the schematic representation utilized in mind mapping eases the twist between the way information is stored on paper and (presumably) in the human memory. All in all I find spending some time on studying docs useful in contrast to the pure work-by-doing approach.
