Hi all,
does anybody know the maximum number of threads libpthread will support on
Linux ? The only information I could find was in
/usr/include/bits/local_lim.h:


/* The number of data keys per process.  */
#define _POSIX_THREAD_KEYS_MAX  128
/* This is the value this implementation supports.  */
#define PTHREAD_KEYS_MAX        1024

and:


/* The number of threads per process.  */
#define _POSIX_THREAD_THREADS_MAX       64
/* We have no predefined limit on the number of threads.  */
#undef PTHREAD_THREADS_MAX


Cheers,
Gabriel.
