\fBcc\fR [ \fIflag\fR ... ] \fIfile\fR ... \fB-lsasl\fR   [ \fIlibrary\fR ... ]
#include <sasl/sasl.h>

\fBint\fR \fBsasl_getrealm_t\fR(\fBvoid *\fR\fIcontext\fR, \fBint\fR \fIid\fR, \fBconst char **\fR\fIavailrealms\fR,

.SH DESCRIPTION
.sp
.LP
Use the \fBsasl_getrealm_t()\fR functionwhen there is an interaction with \fBSASL_CB_GETREALM\fR as the type.
.sp
.LP
If a mechanism would use this callback, but it is not present, then the first realm listed is automatically selected. A mechanism can still force the existence of a getrealm callback by \fBSASL_CB_GETREALM\fR to its \fBrequired_prompts\fR list.
