Hi,
The getpid() call on my Redhat9 linux box is causing
some trouble for SQLite. It's reasonably complicated,
but SQLite currently assumes that on linux the
getpid() function returns a different value in different threads. Not so for my setup!
The attachment is a program to test this. If a few
kind people with linux boxes could compile, run and send me the results of it that would help me out.
To compile do:
$ gcc -pthread tst_getpid.c -o tst_getpid
It will take a few seconds to print out 5 lines of
the form "pid is XXX". I need to know whether or not
all 5 XXX numbers are the same or distinct.
Please include the output of command 'uname -a' and your distro if you can do this.
Thanks enormously,
Dan.
