What would be of great help is concise guide on how migrate of the libc
functionalities (a wiki page?). I'm porting to fpc Kylix projects which
used libc. Reading this mailing list I realized that libc wasn't the way
to go, but I had a hell of a time to discover the equivalents, scattered
in SysUtils, Unix, UnixUtils,BaseUnix, sometimes with different names,
different parameters, etc.
Sort of:
libc.getenv -> SysUtils.GetEnvironmentVariable
Someone with a good knowledge of fpc should be able to do it in a short
time.
I usually use grep when I require to find things. I personally do not
understand why the unix units contain function names with the prefix
of Fp, but it does not matter, because the name remains, so I do
something like
grep -in functionname ./location/* -R | grep -v "something I do not
wish to be included"
And I find what/where what I wish to have is located... It's good btw
for anything you do not remember/know where/how it is located ...
Tanks for the hint, but grep (or Find in Files from IDE) has the big
disadvantage that you don't find only the declaration, but also all the
references. You search "FindFirst" and you find 200 entries...
Moreover if you search e.g. execvp, you'll never find TProcess, which is
the recommended way to start an external application.
That's why some help from developers, or experienced users, would be
more than welcome.
