# include <stdlib.h>
The ISO C standard introduced this header file as a place to declare certain standard library functions. These include the Memory management functions (malloc, free, et. al.) communication with the environment (abort, exit) and others. Not yet all the standard functions of this header file are supported. If a dlaration is present in the supplied header file, then uCR supports it and will continue to support it. If a function is not there, it will be added in time.
