`system' return code not (portably) interpretable #249

Open hyln9 opened 10 years ago

hyln9 commented 10 years ago

The integer returned by the 'system' procedure is not (portably) interpretable by Scheme code (in C it as to be destructured by the WIFEXITED() macro & co.):

> (system "exit 1")
256

As there is already code to interpret that integer for implementing wstatus-exit-code' andwstatus-received-signal', this functionality should probably refactored to expose a procedure to destructure the return value of `system' as well.
