The value of PTHREAD_DESTRUCTOR_ITERATIONS is - provided by the - CYGNUM_POSIX_PTHREAD_DESTRUCTOR_ITERATIONS - option. This controls the number of times that a key destructor - will be called while the data item remains non-NULL. -
The value of PTHREAD_KEYS_MAX is provided - by the CYGNUM_POSIX_PTHREAD_KEYS_MAX - option. This defines the maximum number of per-thread data items - supported. The POSIX standard calls for this to be a minimum of - 128, which is rather large for an embedded system. The default - value for this option is set to 128 for compatibility but it - should be reduced to a more usable value. -
