Dear list
I decided to revive an old monitoring program I once wrote for NetBSD
and adapted it to FreeBSD's system calls.
One of the probes is supposed to check, if a process is still running.
When compiling, clang barfs:
---------------------------- 8< ----------------------------
clang -c -Wall psprobe-BSD.c
psprobe-BSD.c:65:48: error: subscript of pointer to incomplete type 'struct kinfo_proc'
snprintf(CommandString, 64, "%s: ", processes[i].p_comm);
~~~~~~~~~^
/usr/include/kvm.h:56:8: note: forward declaration of 'struct kinfo_proc'
struct kinfo_proc;
^
---------------------------- 8< ----------------------------
What I don't understand is: why isn't struct kinfo_proc completely
defined there? I couldn't find it's definition below /usr/include
anywhere.
Can anybody give me a hint?
I'll gladly send the complete file to the list if that's appropriate.
Thanks
Chris
