bson_append_oid - bson_append_oid()

#define BSON_APPEND_OID(b, key, val) \

bson_append_oid (b, key, (int) strlen (key), val) bool bson_append_oid (bson_t *bson,
const char *key,
int key_length,
const bson_oid_t *oid);


  • bson: A bson_t.
  • key: An ASCII C string containing the name of the field.
  • key_length: The length of key in bytes, or -1 to determine the length with strlen().
  • oid: A bson_oid_t.

The bson_append_oid() function shall append a new element to bson of type BSON_TYPE_OID. oid MUST be a pointer to a bson_oid_t.

Returns true if the operation was applied successfully. The function will fail if appending oid grows bson larger than INT32_MAX.
