> >The errno.h header file claims errno is set by "system functions". >Does anyone know how to set errno in C6.0? > Yes, you are correct about the thread influence on errno. Setting errno is pretty no-standard as your finding out, perhaps a better way might be to add your own error handling system. Such as; .. n = read(fd,&i,2); if (n<0) SetOurError(errno); // to trap system errors .. SetOutError(some_error_number); // and to generate your own. .. or; (if your a fan of Global Variables) .. n = read(fd,&i,2); if (n<0) ErrorCode=errno; // to trap system errors .. ErrorCode=some_error_number; // and to generate your own. .. -- Jack Computer Support Corporation Dallas,Texas Hudler Internet: jack@cscdec.cs.com
