NAME
mongoc_client_set_write_concern() - None
SYNOPSIS
void
mongoc_client_set_write_concern (mongoc_client_t *client,
const mongoc_write_concern_t *write_concern);
Sets the write concern for the client. This only affects future operations, collections, and databases
inheriting from client \&.
The default write concern is MONGOC_WRITE_CONCERN_W_DEFAULT: the driver blocks awaiting basic
acknowledgment of write operations from MongoDB. This is the correct write concern for the great majority
of applications.
It is a programming error to call this function on a client from a mongoc_client_pool_t \&. For pooled
clients, set the write concern with the MongoDB URI instead.
PARAMETERS
client A mongoc_client_t \&.
write_concern
A mongoc_write_concern_t \&.
