### BDUtilsProgExtract ()

    gboolean
    (*BDUtilsProgExtract) (const gchar *line,
                           guint8 *completion);

Callback function used to process a line captured from spawned command's standard output and standard error output. Typically used to extract completion percentage of a long-running job.

Note that both outputs are read simultaneously with no guarantees of message order this function is called with.

The value the `completion` points to may contain value previously returned from this callback or zero when called for the first time. This is useful for extractors where only some kind of a tick mark is printed out as a progress and previous value is needed to compute an incremented value. It's important to keep in mind that this function is only called over lines, i.e. progress reporting printing out tick marks (e.g. dots) without a newline character might not work properly.

The `line` string usually contains trailing newline character, which may be absent however in case the spawned command exits without printing one. It's guaranteed this function is called over remaining buffer no matter what the trailing character is.

#### Parameters

line | line to extract progress from |
completion | percentage of completion. | [out]

#### Returns

whether the line was a progress reporting line and should be excluded from the collected standard output string or not.

                        gchar *msg);
