Specifically, the return codes are as follows (from dos.h):

#define RETURN_OK                           0  /* No problems, success */
#define RETURN_WARN                         5  /* A warning only */
#define RETURN_ERROR                       10  /* Something wrong */
#define RETURN_FAIL                        20  /* Complete or severe failure*/
