malloc

#include <stdlib.h>

void far *malloc (
  size_t size);   /* block size to allocate */

or

void huge *malloc (
  size_t size);   /* block size to allocate */

or

void xhuge *malloc (
  size_t size);    /* block size to allocate */

The malloc function allocates a memory block from the memory pool of size bytes in length.

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.
• Pointer arguments and return values are far in Small, Medium, Compact, and Large Memory Models; huge in HCompact and HLarge Memory Models; and xhuge in the XLarge Memory Model. This function is not supported in the Tiny Memory Model.
