Ot man perror:
Note that errno is undefined after a successful library call:
this call may well change this variable, even though it
succeeds, for example because it internally used some
other library function that failed.
TR: Sled uspesheno izvikvane na funkcia ot lib errno e v nevalidno
systoianie ...
Ot koeto sledva che vtoroto perror moje da vadi kakvoto si iska.
ako ti triabva da go zapazish moje da probvash slednoto:
int main()
{
int errno_save;
errno_save = errno;
perror("nothing");
errno = errno_save;
perror("perror");
}
Tova ne sym siguren dali raboti ako e v thread.
