Gio.Credentials.set_unix_user

### Method

# Gio Credentialsset_unix_user

since: 2.26

#### Declaration [src]

    gboolean
    g_credentials_set_unix_user (
      GCredentials* credentials,
      uid_t uid,
      GError** error
    )

#### Description [src]

Tries to set the UNIX user identifier on `credentials`. This method is only available on UNIX platforms.

This operation can fail if `GCredentials` is not supported on the OS or if the native credentials type does not contain information about the UNIX user. It can also fail if the OS does not allow the use of “spoofed” credentials.

Available since: 2.26

#### Parameters

`uid`

  Type: `uid_t`

  The UNIX user identifier to set.

`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: `gboolean`

`TRUE` if `uid` was set, `FALSE` if error is set.
