New Revision: 3480
URL: http://svn.digium.com/view/zaptel?view=rev&rev=3480
Log:
checkpoint where tone playback code has all been updated (but no code to feed int generated tones yet):
remove tones.h and gendigits from svn:ignore as they will be going away
remove tones.h from Makefile
improve digits.h to use C99-style initializers and define default tone lengths in terms of ZT_CHUNKSIZE instead of hardcoded value
add ZT_TONE_MF_* values to zaptel.h to support sending MF tones via ZT_SENDTONE
change zt_dtmf_tone() to take a zt_chan pointer so it can get the curzone from the channel
set txdialbuf in the zt_chan to uppercase on receipt from userspace so the code using the buffer doens't have to check for both upper and lowercase characters
cleanup and simplify zt_dtmf_tone() and __do_dtmf()
don't allow a tonezone to be set with ZT_DEFAULTZONE if it hasn't been loaded
don't allow a tonezone to be freed with ZT_FREEZONE it if is the default zone
when setting tone length with ZT_SET_DIALPARAMS, do it for all loaded zones
use the default zone for tone length to be returned by ZT_GET_DIALPARAMS
clean up and fix one possible buffer overflow in ZT_DIAL_OP_APPEND
remove dtmf_tones_continuous and mf_tones_continuous global arrays
