THR_EXIT(2) System Calls Manual THR_EXIT(2)

NAME

thr_exit —
terminate current thread

LIBRARY

Standard C Library (libc, -lc)

SYNOPSIS

#include <sys/thr.h>

void
thr_exit(long *state);

DESCRIPTION

This function is intended for implementing threading. Normal applications should call pthread_exit(3) instead.

The thr_exit() system call terminates the current kernel-scheduled thread.

If the state argument is not NULL, the location pointed to by the argument is updated with an arbitrary non-zero value, and an _umtx_op(2) UMTX_OP_WAKE operation is consequently performed on the location.

Attempts to terminate the last thread in the process are silently ignored. Use _exit(2) syscall to terminate the process.

RETURN VALUES

The function does not return a value. A return from the function indicates that the calling thread was the last one in the process.

SEE ALSO

STANDARDS

The thr_exit() system call is non-standard and is used by 1:1 Threading Library (libthr, -lthr) to implement IEEE Std 1003.1-2001 (“POSIX.1”) pthread(3) functionality.
