git_repository_hashfile

Version:

Calculate hash of file using repository filtering rules.

If you simply want to calculate the hash of a file on disk with no filters, you can just use the git_odb_hashfile() API. However, if you want to hash a file in the repository and you want to apply filtering rules (e.g. crlf filters) before generating the SHA, then use this function.

Signature

Parameters

git_oid *
In
