Subject: include/inst: Make inst_stop emit a meaningful message upon error
X-Git-Url: https://git.corax.cc/?a=commitdiff_plain;h=eb3d6f97936dce487812464bda03de139a3eae8c;p=toolbox

include/inst: Make inst_stop emit a meaningful message upon error

Instead of emitting a user-understandable error message, the inst_stop()
function merely lets an error message from the sem module slip through.
This commit changes the function to emit an error message that tells the
caller why exactly the function failed.
