GLib.file_error_from_errno
Description: Reference for GLib.file_error_from_errno

### Function

# GLibfile_error_from_errno

#### Declaration [src]

    GFileError
    g_file_error_from_errno (
      gint err_no
    )

#### Description [src]

Gets a `GFileError` constant based on the passed-in `err_no`.

For example, if you pass in `EEXIST` this function returns `G_FILE_ERROR_EXIST`. Unlike `errno` values, you can portably assume that all `GFileError` values will exist.

Normally a `GFileError` value goes into a `GError` returned from a function that manipulates files. So you would use `g_file_error_from_errno()` when constructing a `GError`.

#### Parameters

`err_no`

  Type: `gint`

  An “errno” value.

#### Return value

Type: `GFileError`

`GFileError` corresponding to the given `err_no`.
