- 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 linkzmq: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.
- SEE ALSO
- --------
