Equivalent of SDL_AudioSpec (Midi Synth Plugin)

I want to implement GitHub - schellingb/TinySoundFont: SoundFont2 synthesizer library in a single C/C++ file to make Midi Synthesizer. But, i not found equivalent of SDL_AudioSpec.callback to apply Audio modification.

Example:

github.com

schellingb/TinySoundFont/blob/master/examples/example2.c

#include "minisdl_audio.h"

#define TSF_IMPLEMENTATION
#include "../tsf.h"

// Holds the global instance pointer
static tsf* g_TinySoundFont;

// A Mutex so we don't call note_on/note_off while rendering audio samples
static SDL_mutex* g_Mutex;

static void AudioCallback(void* data, Uint8 *stream, int len)
{
	// Render the audio samples in float format
	int SampleCount = (len / (2 * sizeof(float))); //2 output channels
	SDL_LockMutex(g_Mutex); //get exclusive lock
	tsf_render_float(g_TinySoundFont, (float*)stream, SampleCount, 0);
	SDL_UnlockMutex(g_Mutex);
}
