   ANSI

Description

   malloc allocates a block of memory that is numbytes in size. If numbytes
   is 0, NULL is returned.

Example 

   #include <stdlib.h>
   #include <stdio.h>
   #define NUM_INTS 7623

   int main()
   {
   int *memblock;

       memblock = malloc(NUM_INTS*sizeof(int));
       if(memblock == NULL) {
           printf("Insufficient memory\n");
           return EXIT_FAILURE;
       }
       else
           printf("Memory allocated\n");
       free(memblock);
       return EXIT_SUCCESS;
   }

Return Value

   Pointer to the memory block allocated. NULL is returned if not enough
   memory is available, or if numbytes is 0.
