133remctl_error \- Retrieve the error from a failed remctl operation

137.PP
138const char *\fBremctl_error\fR(struct remctl *\fIr\fR);
139.SH "DESCRIPTION"
140.IX Header "DESCRIPTION"
141\&\fIremctl_error()\fR returns the error from a previously failed remctl
142operation.  Its only argument is a remctl struct as returned by
143\&\fIremctl_new()\fR.  If the previous remctl operation was successful, returns
144the constant string \*(L"No error\*(R".
145.PP
146The caller may not modify the returned string.  The string may even be
147stored in read-only memory and attempting to modify it may cause a memory
148fault.  The returned pointer will be invalidated by the next call to any
149remctl \s-1API\s0 function with the same client object, other than
150\&\fIremctl_error()\fR.
151.SH "RETURN VALUE"
152.IX Header "RETURN VALUE"
153\&\fIremctl_error()\fR returns either the previous error or the constant string
154\&\*(L"No error\*(R".  It will never return \s-1NULL\s0.
