#define | EDOM 33 |
#define | ERANGE 34 |
#include <errno.h>
Some functions in the library set the global variable errno
when an error occurs. The file, <errno.h>
, provides symbolic names for various error codes.
errno
global variable is not safe to use in a threaded or multi-task system. A race condition can occur if a task is interrupted between the call which sets error
and when the task examines errno
. If another task changes errno
during this time, the result will be incorrect for the interrupted task. #define EDOM 33 |
Domain error.
#define ERANGE 34 |
Range error.
