Synopsis

bool
mongoc_cursor_next (mongoc_cursor_t *cursor, const bson_t **bson);

Parameters

Description

This function shall iterate the underlying cursor, setting bson to the next document.

This function is a blocking function.

Returns

This function returns true if a valid bson document was read from the cursor. Otherwise, false if there was an error or the cursor was exhausted.

Errors can be determined with the mongoc_cursor_error() function.
