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().
RETURNS
An integer representing the key length.
SEE ALSO:
bson_iter_key() to retrieve current key.
