Does it defeat the entire purpose of a qelem to include a while loop 

I'm reading data from a buffer...something like:

San Francisco, CA    Work: 857-544-3967

Does it defeat the entire purpose of a qelem to include a while loop  
in it?

if (datainbuffer) {
	read some;
}
	qelem_set(*qe);

qelems-and-while-loops

Depends on what your purpose is in using the qelem. Typically, you 

use it to either make sure that something happens in the low-priority 

thread, or to break up a longer process into bite-sized chunks. In 

any case, the two functions that you show aren't really that 

different, except that the while() version could spin longer 

(potentially indefinitely). If datainbuffer will always be false 

after a read, they are functionally identical.

while(1) ; in a qelem will hang Max, just as while(1) ; in new() or

while(1) ; in a qelem will hang Max, just as while(1) ; in new() or  
free() would.
