Example: return

The following example allocates a memory buffer using the malloc function. If allocation is unsuccessful, the function returns with a -1 value. If successful, the function continues and returns 0 at completion.

    #include <malloc.h>
    char * buf;
    if ((buf = (char *)malloc(1024, sizeof(char))) == NULL) {
        lr_output_message ("Insufficient memory available");
        return -1;
    lr_output_message ("Memory allocated - buffer address = %.8Xh", buf);
    // Do something with the buffer here ... 
    // Now free the buffer
Action.c(11): Memory allocated - buffer address = 007B9D88h
