older disk-based cmix instruments
inrepos is superceded by rtinrepos. There is no equivalent for outrepos in RTcmix because of the way the scheduler works, The alternative is to use the scheduler to set the timepoint for output-writing.
From the source code:
int inrepos(int samps, int fno)
samps = number of samples to move forwards or backwards (negative) in time
fno = open soundfile number
int outrepos(int samps, int fno)
samps = number of samples to move forwards or backwards (negative) in time
fno = open soundfile number
Both functions return a pointer to the file being operated upon, or exit on failure.
