Ggit.Blame.from_buffer

### Method

# Ggit Blamefrom_buffer

#### Declaration [src]

    GgitBlame*
    ggit_blame_from_buffer (
      GgitBlame* blame,
      const guint8* buffer,
      gsize buffer_length,
      GError** error
    )

#### Description [src]

Get blame data for a file that has been modified in memory. `blame` is a pre-calculated blame for the in-odb history of the file. This means that once a file blame is completed (which can be expensitve), updating the buffer blame is very fast.

Lines that differ between the buffer and the committed version are marked as having a zero id for their #ggit_blame_hunk_get_final_commit_id.

#### Parameters

`buffer` | An array of `guint8`
| The contents of the file.
| The length of the array is specified in the `buffer_length` argument.
| The data is owned by the caller of the function.
`buffer_length` | `gsize`
| The length of the buffer.
`error` | `GError **`
| The return location for a `GError*`, or `NULL`.

#### Return value

Returns: | `GgitBlame`
| A `GgitBlame` or `NULL`.
| The caller of the method takes ownership of the data, and is responsible for freeing it.
| The return value can be `NULL`.
