[Help-glpk] Avoiding 'display' of messages?

[Philip Warner]

I use glpk as a windows DLL, and wish to avoid it trying to display 
messages, if possible. I notice that mip_create_tree has a msg_lev field in 
the tree:

      tree->msg_lev = 3;

which is checked before each call to display.

For a DLL, the ideal would be an (optional) callback, which if not 
specified would result in no output. Alternatively, a supported way of 
setting msg_lev to 0 would be good.

Is this kind of feature appealing to other people? Does anybody have a 
suggestion of the best way to achieve either objective? I appreciate that 
glpk is multiplatform, so there may be obstacles to using callbacks that I 
am unaware of.
