git_object_lookup_prefix

Version:

Lookup a reference to one of the objects in a repository, given a prefix of its identifier (short id).

The object obtained will be so that its identifier matches the first 'len' hexadecimal characters (packets of 4 bits) of the given id. len must be at least GIT_OID_MINPREFIXLEN, and long enough to identify a unique object matching the prefix; otherwise the method will fail.

The generated reference is owned by the repository and should be closed with the git_object_free method instead of free'd manually.

The type parameter must match the type of the object in the odb; the method will fail otherwise. The special value GIT_OBJECT_ANY may be passed to let the method guess the object's type.
