"POSIX multithreaded programming," notes (2) the author himself wrote two source code debugging macro function

When beginning to see the first few "alarm" code errors.h Where children did not find the original. . .

    pthread_t Thread; int Status; / * from deadlock example: 
     * in most cases, uninitialized variable pthread_t is an invalid thread ID, the calling thread recovery function normally check out the cause of the error; 
            but there may be an uninitialized value is a valid ID, at this time, this thread entered from the deadlock. * / 
    Status = pthread_join (Thread, NULL);
     iF (! Status = 0 ) 
    { / *


    

    
         the strerror:
         When information of interest * is different from perror errno current corresponding to the standard error,
         * Strerror errno is designated a, and returns an error string, the device is not redirected to the standard. * / 
        Fprintf (stderr, " error% D:% S \ n- " , Status, the strerror (Status));
