NAME¶
zmq_init - initialise 0MQ context
SYNOPSIS¶
void *zmq_init (int io_threads);
DESCRIPTION¶
The
zmq_init() function initialises a 0MQ
context.
The
io_threads argument specifies the size of the 0MQ thread pool to
handle I/O operations. If your application is using only the
inproc
transport for messaging you may set this to zero, otherwise set it to at least
one.
Thread safety. A 0MQ
context is thread safe and may be shared
among as many application threads as necessary, without any additional locking
required on the part of the caller.
RETURN VALUE¶
The
zmq_init() function shall return an opaque handle to the initialised
context if successful. Otherwise it shall return NULL and set
errno to one of the values defined below.
ERRORS¶
EINVAL
An invalid number of io_threads was
requested.
