NAME

|
----
|
|
zmq_strerror - get 0MQ error message string
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
*const char *zmq_strerror (int 'errnum');*
|
|
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
The _zmq_strerror()_ function shall return a pointer to an error message string
|
|
corresponding to the error number specified by the 'errnum' argument. As 0MQ
|
|
defines additional error numbers over and above those defined by the operating
|
|
system, applications should use _zmq_strerror()_ in preference to the standard
|
|
_strerror()_ function.
|
|
|
|
|
|
RETURN VALUE
|
|
------------
|
|
The _zmq_strerror()_ function shall return a pointer to an error message
|
|
string.
|
|
