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
free(buf);
Example: Output:
Action.c(11): Memory allocated - buffer address = 007B9D88h
