.SH "NAME"
zmq_strerror \- get 0MQ error message string
.SH "SYNOPSIS"
.sp
\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"
.sp
No errors are defined\&.
.SH "EXAMPLE"
.PP
\fBDisplaying an error message when a 0MQ context cannot be initialised\fR.
.sp
.if n \{\
.RS 4
.\}
.nf
void *ctx = zmq_init (1, 1, 0);
if (!ctx) {
printf ("Error occurred during zmq_init(): %s\en", zmq_strerror (errno));
abort ();
}
