I am upgrading an app that used to play wav files when sounds were needed. These sounds were played either directly from file, or from memory if they had previously been loaded into memory. (the commonly used sounds were loaded into memory in order to speed up latency on playing)

sndPlaySound (The API predecessor to PlaySound) was used to play the wav files from memory or from file as needed (by setting the SND_MEMORY flag). Can I achieve the same thing with mciSendString or mciSendCommand?

Also does anybody know where I could find out what can actually be done with the mci Functions, since all I seem to be able to find is the parameter info?
