Subject: opt_to_gvar: notify the user in case of invalid values for --config
X-Git-Tag: sigrok-cli-0.6.0~46
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=27d310f019395f2e4d5615b3f88b7255655a8039;p=sigrok-cli.git

opt_to_gvar: notify the user in case of invalid values for --config

sigrok-cli exits silently in many cases where values passed to --config are
empty strings or haven't been converted by GLib functions properly.

Check for errors and notify the user.
