My pthread_t actually IS an integer, but I also want this to be portable. Smilie I just solved my problem though -- I totally misunderstood pthread keys, I thought there was only one value per key when there's actually one value PER THREAD per key. So I can create one totally global key and store a unique integer for each thread in it Smilie

PTHREAD_EQUAL(3)					     Linux Programmer's Manual						  PTHREAD_EQUAL(3)

NAME
pthread_equal - compare thread IDs SYNOPSIS
#include <pthread.h> int pthread_equal(pthread_t t1, pthread_t t2); Compile and link with -pthread. DESCRIPTION
The pthread_equal() function compares two thread identifiers. RETURN VALUE
If the two thread IDs are equal, pthread_equal() returns a nonzero value; otherwise, it returns 0. ERRORS
This function always succeeds. CONFORMING TO
POSIX.1-2001. NOTES
The pthread_equal() function is necessary because thread IDs should be considered opaque: there is no portable way for applications to directly compare two pthread_t values. SEE ALSO
