  29  * Support for thr_debug.c:
  30  *
  31  * thr_debug.c defines ldap_pvt_thread_* as wrappers around the real
  32  * ldap_pvt_thread_* implementation, which this file renames to
  33  * ldap_int_thread_*.
  34  *
  35  * Implementation:
  36  *
  37  * This file re#defines selected ldap_pvt_thread_* names to
  38  * ldap_int_thread_*, which will be used from wrappers in thr_debug.c.
  39  * Two ldap_int_*() calls are redirected to call ldap_debug_*(): These
  40  * are wrappers around the originals, whose definitions are not renamed.
  41  * This file then #includes ldap_pvt_thread.h to declare the renamed
  42  * functions/types.  If #included from thr_debug.c it finally #undefines
  43  * the macros again.
  44  *
  45  * include/ldap_pvt_thread.h declares the typedefs ldap_pvt_thread*_t as
  46  * either wrapper types ldap_debug_thread*_t or their usual definitions
  47  * ldap_int_thread*_t, depending on the LDAP_THREAD_DEBUG_WRAP option.
  48  * When defining the underlying implementation, this file then redirects
  49  * the type names back to the original ldap_int_thread*_t types.
  50  * include/ldap_<int,pvt>_thread.h also do some thr_debug magic.
  51  *
  52  * So,
  53  * libldap_r/<not thr_debug.c> thus define ldap_int_thread_*() instead
  54  * of ldap_pvt_thread_*().
  55  * thr_debug.c defines the ldap_pvt_*() and ldap_debug_*() functions.
  56  * In thread.c, ldap_pvt_thread_<initialize/destroy>() will call
  57  * ldap_debug_thread_*() instead of ldap_int_thread_*().
  58  * In tpool.c, ldap_int_thread_pool_shutdown() has explicit thr_debug.c
  59  * support which treats ldap_pvt_thread_pool_destroy() the same way.
