In response to similar emails rev'd, I was sitting in front of a linux box at
the
time of the LD_PRELOAD posting, thus my code reflects this. However, Solaris
2.6 should support PTRACE_PEEKUSR as this was favoured over PTRACE_READDATA
in 2.5 I believe (correct me if I'm wrong). In any case, look at <sys/ptrace.h>
for valid request types. The value of EBX is defined in <asm/ptrace.h> and is 0.
If all else fails, you can always issue ioctl routines on a process within the
/proc filesystem ;)
