    NAME

    
    
    pthread_sigmask
    
     - examine and/or change a thread's signal mask
    
     
    

    LIBRARY

    Lb libpthread
    
     
    

    SYNOPSIS

       #include <pthread.h>
       #include <signal.h>
    int pthread_sigmask (int how const sigset_t *set sigset_t *oset);
     

    DESCRIPTION

    The pthread_sigmask ();
    function examines and/or changes the calling thread's signal mask.

    If Fa set is not NULL it specifies a set of signals to be modified, and Fa how specifies what to set the signal mask to:

    SIG_BLOCK
    Union of the current mask and Fa set .
    SIG_UNBLOCK
    Intersection of the current mask and the complement of Fa set .
    SIG_SETMASK
    Fa set .

    If Fa oset is not NULL, the previous signal mask is stored in the location pointed to by Fa oset .

    SIGKILL and SIGSTOP cannot be blocked, and will be silently ignored if included in the signal mask.  

    RETURN VALUES

    If successful, pthread_sigmask ();
    returns 0. Otherwise, an error is returned.  

    ERRORS

    The pthread_sigmask ();
    function will fail if:

    Bq Er EINVAL
    Fa how is not one of the defined values.
