please take this with a grain of salt, and my apologies offered if i come over too strong. i beg you to read on and think twice about it, i'm trying to help even if i may not find the right words.
personally at this particular point i find the documentation rather obscures than explains the matter. read on, please. i have never done pcm io before, not to speak of mmap'd pcm io. paul's comment was very helpful to me, if only it was because he did explain what the parameters of the mmap_commit call are used for. [i have more grievances. for example, the mmap_begin documentation says about the offset returned: * \param offset Returned mmap area offset but with not a word is mentioned that the offset value is counting bits which may be usual in the pcm world while in overall programming it is not.] you surely are gifted hackers (the ALSA design proves it i think) - but you should take into account that somebody who uses your API may not even know a fraction of what you know about pcm card and driver design, in fact they may even do this for the first time. *please* adjust your documentation policy from 'we need mathematical correctness' to 'we need to help those stupids like tim out there by being verbose to the extent of repetition, otherwise nobody can use our API simply because they do not understand it'. tim _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
