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() .

Adding an "extern int errno;" at global level in module cleared problem. errno. Global error variable. Synopsis: #include extern int errno; char * const sys_errlist[]; int sys_nerr; Library: libc. Use the -l c option to qcc to link against this library.

#define errno /*implementation-defined*/ errno is a preprocessor macro used for error indication. It expands to a static (until C++11) thread-local (since C++11) modifiable lvalue of type int. Several standard library functions indicate errors by writing positive integers to errno.

Declaration Following is the declaration for errno macro. extern int errno; (without including ) is unsupported. It is unspecified whether 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 errno, the behavior is undefined. extern tells the compiler that this data is defined somewhere and will be connected with the linker.

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. Latest commit 896b8d3 on Jun 26, 2019 History.
