mongoc_client_set_appname - Man Page

bool
mongoc_client_set_appname (mongoc_client_t *client, const char *appname)

Sets the application name for this client. This string, along with other internal driver details, is sent to the server as part of the initial connection handshake ("hello" <https://www.mongodb.com/docs/manual/reference/command/hello/>).

appname is copied, and doesn't have to remain valid after the call to mongoc_client_set_appname().

This function will log an error and return false in the following cases:

• appname is longer than MONGOC_HANDSHAKE_APPNAME_MAX
• client has already initiated a handshake
• client is from a mongoc_client_pool_t <>

• client: A mongoc_client_t <>.
• appname: The application name, of length at most MONGOC_HANDSHAKE_APPNAME_MAX.

true if the appname is set successfully. Otherwise, false.
