+.Sh NAME
+.Nm pthread_switch_add_np ,
+.Nm pthread_switch_delete_np
+.Nd threads context switches debugging primitives
+.Sh LIBRARY
+.Lb libc_r
+.Sh SYNOPSIS
+.In pthread_np.h
+.Ft int
+.Fn pthread_switch_add_np "pthread_switch_routine_t routine"
+.Ft int
+.Fn pthread_switch_delete_np "pthread_switch_routine_t routine"
+.Sh DESCRIPTION
+The application is allowed to monitor thread context switches inside
+threading library.
+An application can install routine that gets called everytime a thread
+(explicitly created by the application with
+.Fn pthread_create
+function) gets context switched.
+This routine gets passed the pthread IDs of the threads that are
+being switched in and out.
+Installation and removal of these hooks may be done using
+.Fn pthread_switch_add_np
+and
+.Fn pthread_switch_delete_np
+functions respectively.
+.Sh RETURN VALUES
+If successful,
+functions return 0. 
+Otherwise, an error number is returned to indicate the error.
+.Sh ERRORS
+The
+.Fn pthread_switch_add_np
+may fail if:
