BSON_ITER_KEY_LEN(3) | Libbson | BSON_ITER_KEY_LEN(3) |
NAME¶
bson_iter_key_len - bson_iter_key_len()SYNOPSIS¶
uint32_t bson_iter_key_len (const bson_iter_t *iter);
PARAMETERS¶
- •
- iter: A bson_iter_t.
DESCRIPTION¶
Fetches the length of the key for the current element observed by iter. This is a constant time computation, and therefore faster than calling strlen() on a key returned by bson_iter_key().SEE ALSO¶
bson_iter_key() to retrieve current key.RETURNS¶
An integer representing the key length.AUTHOR¶
