ZMQ_INIT(3) 0MQ Manual ZMQ_INIT(3)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.
This function is deprecated by zmq_ctx_new(3).
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.
