Why RCC_AHBPeriphClockCmd is used?

Hi,
I have been  studying the SMT32F code and have seen this function being used extensively in the initialization routine.

RCC_AHBPeriphClockCmd(RCC_AHBPeriph_FSMC or RCC_AHBPeriph_SDIO, DISABLE/ENABLE);

Can someone please  suggest the ST library Documentation as well as the usage of this method.
Also what will happen if I don't use it.
Rgds,
Softy
