ssh_channel_read - expected behavior?

[Jonathan Walker <jwalker@xxxxxxxxxxxx>]

Hello,

My colleague and I updated our LibSSH library to the most recent source tree around mid-August (we manually built the library).  We noticed that the function "ssh_channel_read" began to behave a bit differently from the previous 0.5.0 library.  I also noticed from the release note of 0.5.2 the following:
o
Fixed possible infinite loop in channel_read().

This leads me to believe that there was indeed a functionality change.  We have been noticing that the function periodically returns even if no bytes have been read.  I would assume that this is to prevent getting stuck in the infinite loop as addressed in the note.  Could I get a bit more detail on the expected functionality of this function call?  Can we expect that the function return within x seconds (even if no bytes have been read)?

Thanks so much,
Jonathan
