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`

  Type: 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 method.

`buffer_length`

  Type: `gsize`

  The length of the buffer.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the method if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: `GgitBlame`

A `GgitBlame` or `NULL`.

The caller of the method takes ownership of the returned data, and is responsible for freeing it.
The return value can be `NULL`.
