Hello,.. few minutes ago i was noted that using extern int errno is actually a mistake but the problem is that as far as i remember coding in C (the last year) i used that form. 2003-11-29 · */ 00027 00028 #ifndef _ERRNO_H 00029 #define _ERRNO_H 00030 00031 00032 #ifdef __cplusplus 00033 extern "C" { 00034 #endif 00035 00036 #define EPERM 1 /* Operation not permitted */ 00037 #define ENOENT 2 /* No such file or directory */ 00038 #define ESRCH 3 /* No such process */ 00039 #define EINTR 4 /* Interrupted system call */ 00040 #define extern int h_errno; (without including ) is unsupported. It is unspecified whether h_errno is a macro or an identifier declared with external linkage. If a macro definition is suppressed in order to access the actual object, or a program defines an identifier with the name h_errno, the behavior is undefined.

No matter which thread you're in, you can simply refer to errno — it's defined in such a way that it refers to the correct variable for the thread. For more information, see Local storage for private data in the documentation for ThreadCreate() .

The following sentence is deleted from the DESCRIPTION: "The value of errno is 0 at program start-up, but is never set to 0 by any XSI function". The DESCRIPTION also no longer states that conforming implementations may support the declaration: extern int errno; Issue 6. Obsolescent text regarding defining errno as: extern int errno is removed.

errno is defined with the code #define errno (*_errno()) errno is set on an error in a system-level call. Because errno holds the value for the last call that set it, this value may be changed by succeeding calls. Always check errno immediately before and after a call that may set it.

This library is usually included automatically. Description: The errno variable is set to certain error values by many functions whenever an error has occurred.
