 I've been creating a library with the following command in "linkedit" -

addxl from=mylib;to=myxl;merge; rl=LIBCINIT.LIB.SYS,socketrl.net.sys

"mylib" is a C .a file that I created with "c89" and "ar" at the shell
prompt.

I managed to find out about "socketrl.net.sys" by searching this news
group to resolve the socket calls but there are a few functions I'm
still stuck on -

UNRESOLVED EXTERNALS: srand  (LDRERR 512)
UNRESOLVED EXTERNALS: ioctl  (LDRERR 512)
UNRESOLVED EXTERNALS: sigemptyset  (LDRERR 512)
UNRESOLVED EXTERNALS: sigaction  (LDRERR 512)
UNRESOLVED EXTERNALS: alarm  (LDRERR 512)

I found a posting about "alarm" but it just said to look in
/etc/c89.cfg.   I looked in there and found a line that goes through all
the libraries in "DLibs" and adds them.  But I can't see how "DLibs"
gets set - it's not set in /etc/c89.cfg.

My MPE knowledge is very limited so please keep it simple if anyone has
some advice.

Thanks.

Peter
