+.Dt PTHREAD_ATTR_GET_NP 3
+.Os
+.Sh NAME
+.Nm pthread_attr_get_np
+.Nd get attributes of existing thread
+.Sh LIBRARY
+.Lb libpthread
+.Sh SYNOPSIS
+.In pthread.h
+.Ft int
+.Fn pthread_attr_get_np "pthread_t thread" "pthread_attr_t *attr"
+.Sh DESCRIPTION
+The
+.Fn pthread_attr_get_np
+function can be used to retrieve attributes of a running
+.Fa thread .
+The result is stored to
+.Fa attr ,
+which should be initialized prior to the call by using
+.Xr pthread_attr_init 3 .
+.Pp
+Most fields of
+.Fa attr
+are the same ones provided during thread creation time as a parameter to
+.Xr pthread_create 3 .
+The exceptions include:
+.Bl -bullet -offset indent
+.It
+The detach state -- a joinable thread
+may have detached itself after the creation.
+.It
+The guard size, which may vary if the application
+has allocated its own thread stack.
+.It
+The stack address and size;
+.Fn pthread_attr_get_np
+will always return the thread's real stack address and size,
+regardless of the values in the original attributes structure.
+.El
+.Pp
+The returned
+.Vt pthread_attr_t
+structure is supposed to be used in conjunction with the
+.Fn pthread_attr_get*
+functions to retrieve individual values from the structure.
+When the returned
+.Fa attr
+is no longer needed, it should be destroyed by using
+.Xr pthread_attr_destroy 3 .
+.Sh COMPATIBILITY
+The
+.Fn pthread_attr_get_np
+function is a non-standard extension.
+.Sh RETURN VALUES
+Upon successful completion,
+.Fn pthread_attr_get_np
+returns 0.
+Otherwise an error number is returned to indicate the error.
+.Sh ERRORS
+The
+.Fn pthread_attr_get_np
+function will fail if:
+.Bl -tag -width Er
+.It Bq Er ENOMEM
+Insufficient memory.
+.It Bq Er ESRCH
+Non-existent
+.Fa thread .
+.Sh SEE ALSO
+.Xr pthread 3 ,
+.Xr pthread_attr 3
