Subject: snd_pcm_mmap_writei
Hello All,
Replacing snd_pcm_writei with snd_pcm__mmap_writei gives SEGFAULT in My code.
Works fine with pcm.c. Can ANyone help me on FINDING OUT WHAT MAY BE CAUSE OF SEGFAULT ?
Is any thing specific required for MMAP Write ????
/$$$ Works FINE $$$/
//while ((pcmreturn = snd_pcm_writei(alsaParams->pcm_handle, data, count)) < 0) // ===>>>>Replaced by below LINE
/$$$ SEG FAULT$$$/
while ((pcmreturn = snd_pcm__mmap_writei(alsaParams->pcm_handle, data, count)) < 0) // REPLACED ABOVE NORMAL WRTIE WITH MMAP WRITE
{
/*
* My code
*/
}
Thanks in advance,
Best Regards
