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.
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).

CONFORMING TO
POSIX.1-2001, POSIX.1-2008.
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.

I want to store a bunch of pthread_t types in a hash table, but since pthread_t is not an integer value, I cannot hash it. I was hoping to store a unique nonzero as key 0 for each thread with thread-specific data ala pthread_key_create/pthread_setspecific, but but as it turns out only the first... (2 Replies)
