.IP \(bu 2
\fBbson\fP: A \fBbson_t\fP\&.
.IP \(bu 2

.SH DESCRIPTION
.sp
The \fBbson_append_maxkey()\fP function shall append an element of type BSON_TYPE_MAXKEY to a bson document. This is primarily used in queries and unlikely to be used when storing a document to MongoDB.
.SH RETURNS
.sp
Returns \fBtrue\fP if the operation was applied successfully. The function will fail if appending the value grows \fBbson\fP larger than INT32_MAX.
