- * Read the specified reference from the filesystem or packed refs
- * file, non-recursively. Set type to describe the reference, and:
- *
- * - If refname is the name of a normal reference, fill in sha1
- * (leaving referent unchanged).
- *
- * - If refname is the name of a symbolic reference, write the full
- * name of the reference to which it refers (e.g.
- * "refs/heads/master") to referent and set the REF_ISSYMREF bit in
- * type (leaving sha1 unchanged). The caller is responsible for
- * validating that referent is a valid reference name.
- *
- * WARNING: refname might be used as part of a filename, so it is
- * important from a security standpoint that it be safe in the sense
- * of refname_is_safe(). Moreover, for symrefs this function sets
- * referent to whatever the repository says, which might not be a
- * properly-formatted or even safe reference name. NEITHER INPUT NOR
- * OUTPUT REFERENCE NAMES ARE VALIDATED WITHIN THIS FUNCTION.
- *
- * Return 0 on success. If the ref doesn't exist, set errno to ENOENT
- * and return -1. If the ref exists but is neither a symbolic ref nor
- * a sha1, it is broken; set REF_ISBROKEN in type, set errno to
- * EINVAL, and return -1. If there is another error reading the ref,
- * set errno appropriately and return -1.
- *
- * Backend-specific flags might be set in type as well, regardless of
- * outcome.
- *
- * It is OK for refname to point into referent. If so:
- *
- * - if the function succeeds with REF_ISSYMREF, referent will be
- * overwritten and the memory formerly pointed to by it might be
- * changed or even freed.
- *
- * - in all other cases, referent will be untouched, and therefore
- * refname will still be valid and unchanged.
