NAME¶
<errno.h>: System Errors -Macros¶
#define EDOM 33
Detailed Description¶
#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. Warning:
The 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.
