iv_thread_create
iv_thread(3) ivykis programmer's manual iv_thread(3)NAME
iv_thread_create, iv_thread_set_debug_state - ivykis thread convenience functions
SYNOPSIS
#include <iv_thread.h>
int iv_thread_create(char *name, void (*start_routine)(void *), void *arg);
void iv_thread_set_debug_state(int state);
DESCRIPTION
iv_thread_create is a wrapper around pthread_create(3) which will maintain an ivykis main loop reference in the calling thread (which must
be an ivykis(3) thread, i.e. have had iv_init(3) called in it) for as long as the created thread is alive.
Maintaining a reference on the calling thread's ivykis event loop makes sure that the calling thread will not return from its ivykis main
loop before the created thread exits, as that could cause cleanup still happening in the created thread to be interrupted when the calling
thread subsequently calls exit(3).
The created thread need not be an ivykis thread.
Enabling debugging by calling iv_thread_set_debug with a nonzero argument will print a debug message to standard error whenever a thread is
created via iv_thread_create, whenever a thread so created terminates normally by returning from its start_routine, self-terminates by
calling pthread_exit(3), or is successfully canceled by pthread_cancel(3), and whenever destruction of such a thread is signaled back to
the calling thread.
For inter-thread signaling, iv_thread uses iv_event(3).
