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 determin song position, current options, and any copyright information for handle The indentifier obtained from opening a midi file with WildMidi_Open(3) 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; unsigned long int current_sample; unsigned long int approx_total_samples; unsigned short int mixer_options; }; 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 refered to by handle. You can use this value to determin 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. 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.
