This only affects future operations, collections, and databases inheriting from \fBclient\fP\&. .sp The default write concern is MONGOC_WRITE_CONCERN_W_DEFAULT: the driver blocks awaiting basic acknowledgement of write operations from MongoDB. This is the correct write concern for the great majority of applications. .sp It is a programming error to call this function on a client from a \fBmongoc_client_pool_t\fP\&. For pooled clients, set the write concern with the MongoDB URI instead. .SH PARAMETERS .INDENT 0.0 .IP \(bu 2 \fBclient\fP: A \fBmongoc_client_t\fP\&. .IP \(bu 2 \fBwrite_concern\fP: A \fBmongoc_write_concern_t\fP\&. .UNINDENT .SH AUTHOR MongoDB, Inc .SH COPYRIGHT 2017-present, MongoDB, Inc .\" Generated by docutils manpage writer. .
