and forcing it to be passed as an argument to all the callback
functions for the search routines that require it. Magic now
compiles and runs with the new code, but there are a number of
known issues that need to be fixed up. Committing now so that
I can rebase on the last update to the master branch.
Guided by CodeQL static code analyser.
FileMayNotBeClosed.ql
FileMayNeverBeClosed.ql
The trick with "if(fp != stdout)" is problematic (to analyser) as
technically 'stdout' can be a global pointer that COULD be modified any
time, so it might have changed between the fopen() and fclose() calls so
the close MAY NEVER occurs (which is problem the analyzer can see).
So local state is maintained as a bool which will also clarify to the
compiler see the intention without concern for external stdout
modification.
Some items appear to be out and out leaks when certain commands are use.
This commit makes the code (mostly) C99-compatible, enabling to compile
it without the -Wno-error=implicit-function-declaration flag. This
way, Magic becomes usable on arm64 architectures, specifically on Apple
computers with M1/M2 SoC.
