Making a custom block with no specific/fixed relationship between input and output rates

Hello everyone,

I have a rather open question for you guys this time. I need to make a
custom block with no specific/fixed relationship between input and
output rates. More precisely, the input(s) to my custom block still come
in a streaming fashion but the output is now bursty and aperiodic in
nature. In other words, my custom block should consume/accept the
input(s) at regular rates but should produce (possibly variable number
of)samples at its output(s) only when it pleases. Therefore, I cannot
derive my class from any of the gr_sync_block, gr_block,
gr_sync_decimator, gr_sync_interpolator parent classes. What other
options do I have in my hand to accomplish this job? Any suggestions?

Thanks,
Yu.

You can derive from gr_block. The OFDM detector block does this.
