-.TH PTHREAD_TRYJOIN_NP 3 2015-01-10 "Linux" "Linux Programmer's Manual"
-.SH NAME
-pthread_tryjoin_np, pthread_timedjoin_np \- try to join with a
-terminated thread
-.SH SYNOPSIS
-.nf
-.BR "#define _GNU_SOURCE" " /* See feature_test_macros(7) */"
-.B #include <pthread.h>
-
-.BI "int pthread_tryjoin_np(pthread_t " thread ", void **" retval );
-
-.BI "int pthread_timedjoin_np(pthread_t " thread ", void **" retval ,
-.BI " const struct timespec *" abstime );
-.fi
-.sp
-Compile and link with \fI\-pthread\fP.
-.SH DESCRIPTION
-These functions operate in the same way as
-.BR pthread_join (3),
-except for the differences described on this page.
-
-The
-.BR pthread_tryjoin_np ()
-function performs a nonblocking join with the thread
-.IR thread ,
-returning the exit status of the thread in
-.IR *retval .
-If
-.I thread
-has not yet terminated, then instead of blocking, as is done by
-.BR pthread_join (3),
-the call returns an error.
-
-The
-.BR pthread_timedjoin_np ()
-function performs a join-with-timeout.
-If
-.I thread
-has not yet terminated,
-then the call blocks until a maximum time, specified in
-.IR abstime .
-If the timeout expires before
-.I thread
-terminates,
-the call returns an error.
-The
-.I abstime
-argument is a structure of the following form,
-specifying an absolute time measured since the Epoch (see
-.BR time (2)):
-
-.in +4n
-.nf
-struct timespec {
- time_t tv_sec; /* seconds */
- long tv_nsec; /* nanoseconds */
-};
-.fi
-.in
-.SH RETURN VALUE
-On success,
-these functions return 0;
-on error, they return an error number.
-.SH ERRORS
-These functions can fail with the same errors as
-.BR pthread_join (3).
-.BR pthread_tryjoin_np ()
-can in addition fail with the following error:
-.TP
-.B EBUSY
-.I thread
-had not yet terminated at the time of the call.
-.PP
-.BR pthread_timedjoin_np ()
-can in addition fail with the following errors:
-.TP
-.BR ETIMEDOUT
-The call timed out before
-.I thread
-terminated.
-.TP
-.BR EINVAL
-.I abstime
-value is invalid
-.RI ( tv_sec
-is less than 0 or
-.IR tv_nsec
-is greater than 1e9).
-.PP
-.BR pthread_timedjoin_np ()
-never returns the error
-.BR EINTR .
-.SH VERSIONS
-These functions first appeared in glibc in version 2.3.3.
-.SH CONFORMING TO
-These functions are nonstandard GNU extensions;
-hence the suffix "_np" (nonportable) in the names.
-.SH EXAMPLE
-The following code waits to join for up to 5 seconds:
-
-.nf
- struct timespec ts;
- int s;
-
- ...
-
- if (clock_gettime(CLOCK_REALTIME, &ts) == \-1) {
- /* Handle error */
- }
-
- ts.tv_sec += 5;
-
- s = pthread_timedjoin_np(thread, NULL, &ts);
- if (s != 0) {
- /* Handle error */
- }
-.fi
-.SH SEE ALSO
-.BR clock_gettime (2),
-.BR pthread_exit (3),
-.BR pthread_join (3),
-.BR pthreads (7)
