Re: [Help-glpk] [PATCH] determine whether we are handling an error

[Heinrich Schuchardt]

Hello Jeroen,

could you, please, describe the use case for the patch.

Currently both normal messages and error messages are sent to stdout,
which does not match usual usage of output streams.

I propose to store the information if an error message is written in
env->term_out and to use a new value GLP_ERROR = 2 to indicate an error
message.

This value then should be used in glp_puts to decide if a message shall
be sent to stdout or stderr.

An API function could be provided to read env->term_out. The return
value could be used in the terminal hook function.

Best regards

Heinrich Schuchardt
