-== NAME
-
-nng_thread_create - create thread
-
-== SYNOPSIS
-
-[source, c]
-----
-#include <nng/nng.h>
-
-typedef struct nng_thread nng_thread;
-
-int nng_thread_create(nng_thread **thrp, void (*func)(void *), void *arg);
-----
-
-== DESCRIPTION
-
-The `nng_thread_create()` function creates a single thread of execution,
-running _func_ with the argument _arg_.
-The thread is started immediately.
-A pointer to the thread object is returned in _thrp_.
-
-The intention of this program is to facilitate writing parallel programs.
-Threads created by this program will be based upon the underlying
-threading mechanism of the system that _NNG_ is running on.
-This may include use of coroutines.
-
-Using threads created by this function can make it easy to write
-programs that use simple sequential execution, using functions in the
-_NNG_ suite that would otherwise normally wait synchronously for completion.
-
-When the thread is no longer needed, the
-xref:nng_thread_destroy.3supp.adoc[`nng_thread_destroy()`]
-function should be used to reap it.
-(This function will block waiting for _func_ to return.)
-
-IMPORTANT: Thread objects created by this function may not be real system
-level threads capable of performing blocking I/O operations using normal blocking
-system calls.
-If use of blocking system calls is required (not including APIs provided
-by the _NNG_ library itself of course), then real OS-specific threads
-should be created instead (such as with `pthread_create()` or similar
-functions.)
-
-IMPORTANT: Thread objects created by this function cannot be passed
-to any system threading functions.
-
-TIP: The system may impose limits on the number of threads that can be
-created.
-Typically applications should not create more than a dozen of these.
-If greater concurrency or scalability is needed, consider instead using
-an asynchronous model using xref:nng_aio.5.adoc[`nng_aio`] structures.
-
-TIP: Threads can be synchronized using
-xref:nng_mtx_alloc.3supp.adoc[mutexes] and
-xref:nng_cv_alloc.3supp.adoc[condition variables].
-
-== RETURN VALUES
-
-This function returns 0 on success, and non-zero otherwise.
-
-== ERRORS
-
-[horizontal]
-`NNG_ENOMEM`:: Insufficient free memory exists.

-== NAME
-
-nng_thread_destroy - reap thread
-
-== SYNOPSIS
-
-[source, c]
-----
-#include <nng/nng.h>
-
-void nng_thread_destroy(nng_thread *thread);
-----
-
-== DESCRIPTION
-
-The `nng_thread_destroy()` function reaps the _thread_.
-It waits for the thread function to return, and then deallocates
-the resources for the thread.
-
-IMPORTANT: Do not call this function from the thread function itself,
-or a deadlock will occur.
-
-== RETURN VALUES
-
-None.
-
-== ERRORS
-
-None.

-== NAME
-
-nng_thread_set_name - set thread name
-
-== SYNOPSIS
-
-[source, c]
-----
-#include <nng/nng.h>
-
-void nng_thread_set_name(nng_thread *thread, const char *name);
-----
-
-== DESCRIPTION
-
-The `nng_thread_set_name()` function attempts to set the name for the _thread_ to _name_.
-
-If _thread_ is `NULL`, then the name is set for the current thread.
-
-Support for this, and how names are exposed, varies between platform implementations.
-This function is intended to facilitate debugging applications that may have many threads.
-
-TIP: Internal threads created by _NNG_ will have names beginning with `nng:`.
-
-== RETURN VALUES
-
-None.
-

-None.
