I have written an implementation of read(int, void*, size_t) that I
am trying to use via DYLD_INSERT_LIBRARIES. I have this working fine
on 10.4, but not on 10.5.
I have read http://lists.apple.com/archives/Darwin-dev/2007/Nov/
msg00061.html but am still not clear on what I need to do. A follow
up to that post mentions including a header. I can't seem to find any
detail on this header.
Look at the function prototype declaration in <unistd.h> on 10.5.
You have to do yours the same way. Macros are defined in <sys/
cdefs.h>.
Thanks Stephen,
I tried and no dice.
I am compiling with …
gcc -dynamiclib -o mylib.dylib -fno-common -framework CoreFoundation -
mmacosx-version-min=10.4 mysource.c
Do I need to add something to that?
Specifically, I think I need to provide all 3 symbols (_read, _read
$UNIX2003 and _read$NOCANCEL$UNIX2003) for this to work.
Thanks again,
LD. _______________________________________________
