# WildMidi\_GetInfo(3)

get information on a midi

## NAME

WildMidi\_GetInfo - get information on a midi

## LIBRARY

**libWildMidi**

## SYNOPSIS

**#include \<wildmidi\_lib.h\>**

**struct \_WM\_Info \*WildMidi\_GetInfo (midi \**handle*);**

## DESCRIPTION

Obtains information allowing you to determine song position, current options, and any copyright information.

- *handle*

  The identifier obtained from opening a midi file with [**WildMidi\_Open**(3)](/WildMidi_Open/3.md) **or WildMidi\_OpenBuffer**(3)

## RETURN VALUE

**On error returns NULL with an error message displayed to stderr.**

**Otherwise returns a pointer to a struct containing the information.**

```
struct _WM_Info {
   char *copyright;
   uint32_t current_sample;
   uint32_t approx_total_samples;
   uint32_t total_midi_time;
   uint16_t mixer_options;
   uint32_t total_midi_time;
};
```

- *copyright*

  **A pointer to a \\0 terminated string containing any copyright MIDI events found while processing the MIDI file** *handle* **refers to. If more than one copyright event was found then each one is separated by \\n**

**If** *copyright* **is NULL then no copyright MIDI events were found.**

- *current\_sample*

  **This is the number of stereo samples libWildMidi has processed for the MIDI file referred to by** *handle***. You can use this value to determine the current playing time by dividing this value by the** *rate* **given when libWildMidi was initialized by WildMidi\_Init**(3)**.**

- *approx\_total\_samples*

  **This is the total number of stereo samples libWildMidi expects to process. This can be used to obtain the total playing time by dividing this value by the** *rate* **given when libWildMidi was initialized by WildMidi\_Init**(3). **Also when you divide** *current\_sample* **by this value and multiplying by 100, you have the percentage currently processed.**

- *total\_midi\_time*

  **This is the total time of MIDI events in 1/1000's of a second. It differs from** *approx\_total\_samples* **in that it only states the total time within the MIDI file and does not take into account the extra bit of time to finish playing sampling smoothly.**

- *mixer\_options*

  - WM\_MO\_LOG\_VOLUME

    **Using curved volume settings instead of linear ones.**

  - WM\_MO\_ENHANCED\_RESAMPLING

    **The enhanced resampler is active**

  - WM\_MO\_REVERB

    **Reverb is being added to the final output.**
