SYNOPSIS

uint32_t
bson_iter_key_len (const bson_iter_t *iter);

PARAMETERS

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.
