Parse a hex formatted object id into a git_oid

Copy an already raw oid into a git_oid structure

Format a git_oid into a hex string

Format a git_oid into a loose-object path string

The resulting string is "aa/...", where "aa" is the first two hex digitis of the oid and "..." is the remaining 38 digits.

Format a gid_oid into a newly allocated c-string

Format a git_oid into a buffer as a hex format c-string

If the buffer is smaller than GIT_OID_HEXSZ+1, then the resulting oid c-string will be truncated to n-1 characters. If there are any input parameter errors (out == NULL, n == 0, oid == NULL), then a pointer to an empty string is returned, so that the return value can always be printed.

Copy an oid from one structure to another

Compare two oid structures
