SYNOPSIS

bool
mongoc_collection_insert (mongoc_collection_t *collection,

mongoc_insert_flags_t flags,
const bson_t *document,
const mongoc_write_concern_t *write_concern,
bson_error_t *error);


PARAMETERS

  • collection: A mongoc_collection_t <>.
  • flags: A mongoc_insert_flags_t <>.
  • document: A bson_t <https://www.mongoc.org/libbson/current/bson_t.html>.
  • write_concern: A mongoc_write_concern_t <>.
  • error: An optional location for a bson_error_t <> or NULL.

DESCRIPTION

Note:

To pass additional options, use mongoc_collection_insert_one() <> or mongoc_collection_insert_many() <>.


This function shall insert document into collection.

If no _id element is found in document, then a bson_oid_t <https://www.mongoc.org/libbson/current/bson_oid_t.html> will be generated locally and added to the document. If you must know the inserted document's _id, generate it in your code and include it in the document. The _id you generate can be a bson_oid_t <https://www.mongoc.org/libbson/current/bson_oid_t.html> or any other non-array BSON type.

ERRORS

Errors are propagated via the error parameter.

RETURNS

Returns true if successful. Returns false and sets error if there are invalid arguments or a server or network error.

A write concern timeout or write concern error is considered a failure.
