Note Before calling this function your program must invoke the init_mempool function to initialize the memory management routines and provides the starting address and size of the memory pool. Source code for this routine is provide in the LIB folder. You may modify the source to customize this function for your particular hardware environment.
Return Value	The malloc function returns a pointer to the allocated block or a null pointer if there is not enough memory to satisfy the allocation request.

Example	#include <stdlib.h> #include <stdio.h> /* for printf / void tst_malloc (void) { unsigned char xdata p; p = malloc (1000); /* allocate 1000 bytes */ if (p == 0) printf ("Not enough memory space\n"); else printf ("Memory allocated\n"); }
