LWP_KILL(2) DragonFly System Calls Manual LWP_KILL(2)
NAME
 lwp_kill -- send signal to a lwp
LIBRARY
 Standard C Library (libc, -lc)
SYNOPSIS
 #include <sys/types.h>
 #include <sys/lwp.h>
 #include <signal.h>
 int
 lwp_kill(pid_t pid, lwpid_t tid, int sig);
DESCRIPTION
 The lwp_kill() function sends the signal sig to the lwp specified by pid
 and tid. If pid is -1, the signal will be sent to the current process.
 Permission checking and signal behavior is exactly like in kill(2).
RETURN VALUES
 Upon successful completion, the value 0 is returned; otherwise the
 value -1 is returned and the global variable errno is set to indicate the
 error.
ERRORS
 Lwp_kill() will fail and no signal will be sent if:
 [EINVAL] sig is not a valid signal number.
 [ESRCH] no lwp corresponding to pid and tid can be found.
 [EPERM] the sending process is not the super-user and its
 effective user id does not match the effective user-id
 of the receiving process.
SEE ALSO
 kill(2), lwp_create(2), raise(3)
HISTORY
 The lwp_kill() function first appeared in DragonFly 1.9.
