Re: [Discuss-gnuradio] pre-cog source doubt

Okay I found in older grextras (https://github.com/ncorgan/grextras/blob/master/include/gruel/pmt_mgr.h)

/*
 * ------------------------------------------------------------------------
 *      Manage a collection of PMTs -> memory wise
 *

 * When a PMT reference count becomes zero, the pmt and contents is deleted.

 * With a manager, the PMT will not be deleted, but released to the manager.

 * Then, the PMT can be acquired again for re-use by the user.

 *
 * This offers 2 benefits:
 *  - Avoids expensive memory allocation overhead (re-use is key)
 *  - An upstream producer can block until resources become released
 * ------------------------------------------------------------------------

I was looking at the source of pre-cog and there is this piece of code which i am not able to locate ( pmt_mgr() ) in the documentation.


self.mgr = pmt.pmt_mgr()

for i in range(64):

	self.mgr.set(pmt.pmt_make_blob(10000))

blob = self.mgr.acquire(True )







There is no reference of pmt_mgr in documentation. Can somebody expalain its operation or point to relevant docs.



Thanks
