GetSetTrackSendInfo()

void * GetSetTrackSendInfo(MediaTrack *tr, int category, int sendidx, const char *parmname, void *setNewValue)

category is <0 for receives, 0=sends, >0 for hardware outputs sendidx is 0..n (NULL on any required parameter to stop)

parameter names:

"P_DESTTRACK" (read only, returns MediaTrack *, destination track, only applies for sends/recvs)
"P_SRCTRACK" (read only, returns MediaTrack *, source track, only applies for sends/recvs)
"B_MUTE" (returns bool *, read/write)
"B_PHASE" (returns bool *, read/write - true to flip phase)
"B_MONO" (returns bool *, read/write)
"D_VOL" (returns double *, read/write - 1.0 = +0dB etc)
"D_PAN" (returns double *, read/write - -1..+1)
"D_PANLAW" (returns double *,read/write - 1.0=+0.0db, 0.5=-6dB, -1.0 = projdef etc)
"I_SENDMODE" (returns int *, read/write - 0=post-fader, 1=pre-fx, 2=post-fx(depr), 3=post-fx)
"I_SRCCHAN" (returns int *, read/write - index,&1024=mono, -1 for none)
"I_DSTCHAN" (returns int *, read/write - index, &1024=mono, otherwise stereo pair, hwout:&512=rearoute)
"I_MIDIFLAGS" (returns int *, read/write - low 5 bits=source channel 0=all, 1-16, next 5 bits=dest channel, 0=orig, 1-16=chan)

set setNewValue to non-NULL to set the value
