Re: [Help-glpk] [Fwd: C# Examples for glp_term_hook() and glp_error_hook()]

[Heinrich Schuchardt]

Hello Edmund,

please, call GlpkCallback.addListener to attach your callback method, cf. 
examples/csharp/Gmpl.cs

Call Glpk.glp_ios_terminate(tree) in the callback method when requested by the 
user.

Best regards
