### Method

# Gio Subprocesscommunicate_utf8

since: 2.40

#### Declaration

    gboolean
    g_subprocess_communicate_utf8 (
      GSubprocess* subprocess,
      const char* stdin_buf,
      GCancellable* cancellable,
      char** stdout_buf,
      char** stderr_buf,
      GError** error
    )

#### Description

Like g_subprocess_communicate(), but validates the output of the process as UTF-8, and returns it as a regular NUL terminated string.

On error, `stdout_buf` and `stderr_buf` will be set to undefined values and should not be used.

Available since: 2.40

#### Parameters

`stdin_buf`

  Type: `const char*`

  Data to send to the stdin of the subprocess, or `NULL`.

  A `GCancellable`.

  The argument can be `NULL`.
  The data is owned by the caller of the method.

`stdout_buf`

  Type: `char**`

`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*`.
