zmq_strerror \- get 0MQ error message string

\fBconst char *zmq_strerror (int \fR\fB\fIerrnum\fR\fR\fB);\fR

.SH "DESCRIPTION"
|
||
|
|
.sp
|
||
|
|
The \fIzmq_strerror()\fR function shall return a pointer to an error message string corresponding to the error number specified by the \fIerrnum\fR argument\&. As 0MQ defines additional error numbers over and above those defined by the operating system, applications should use \fIzmq_strerror()\fR in preference to the standard \fIstrerror()\fR function\&.
|
||
|
|
.SH "RETURN VALUE"

||
|
|
.sp
|
||
|
|
The \fIzmq_strerror()\fR function shall return a pointer to an error message string\&.

.SH "ERRORS"
