git_reference_name_to_id

Version:

Lookup a reference by name and resolve immediately to OID.

This function provides a quick way to resolve a reference name straight through to the object id that it refers to. This avoids having to allocate or free any git_reference objects for simple situations.

The name will be checked for validity. See git_reference_symbolic_create() for rules about valid names.
