and we don't want that.
(INCLUDES): Removed all -I options except for the root source
directory and the root build directory.
* *.*: Change includes so that they always use the "prefixes"
libguile/, qt/, guile-readline/, or libltdl/.
(Thanks to Tim Mooney.)
static. It's only useful internally --- you should never just
wait on a condition variable.
* coop-defs.h (coop_condition_variable_wait): Delete prototype.
* threads.h (scm_single_thread_p, scm_yield,
scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
scm_wait_condition_variable, scm_signal_condition_variable): Add
prototypes for these Scheme-visible functions.
* coop-defs.h (coop_next_runnable_thread,
coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
Prototypes for these here, even though they're from iselect.c.
(coop_condition_variable_wait, coop_join): Add prototypes.
* coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
scm_threads_free_condvar): Make these smob functions static.
* coop-threads.h (coop_init): Give this a real prototype.
* coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
(coop_next_runnable_thread): No need to provide prototype; it's in
coop-defs.h.
coop_condition_variable_init, coop_condition_variable_wait,
coop_condition_variable_signal): Changed return type from `void'
to `int'. This is to adhere closer to the pthreads interface.
This, in turn, is part of an attempt to provide C versions of the
mutex and condition variable primitives which can be part of a
frontend to COOP or pthreads.
* coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
coop_condition_variable_destroy): New functions.
* coop-threads.c (scm_wait_condition_variable): Use
coop_condition_variable_wait_mutex.
* coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
Definitions moved to coop-defs.h.
* coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
scm_cond_destroy): New C interface to mutecis and cond vars.
* coop.c (coop_qinit): Initialize fields used by
scm_internal_select.
(coop_qget, coop_qget, coop_tmp_queue): Made global.
(coop_next_runnable_thread): If GUILE_ISELECT enabled, use
replacement in iselect.c.
(coop_mutex_lock, coop_condition_variable_wait, coop_abort,
coop_join): If GUILE_ISELECT enabled, use
coop_wait_for_runnable_thread instead of
coop_next_runnable_thread.
(usleep, sleep): New replacements for system functions if
GUILE_ISELECT is enabled.
* coop-threads.h: Declare coop_wait_for_runnable_thread.
* coop-defs.h (coop_t): Added fields used by scm_internal_select.
* filesys.c: Added #include "iselect.h". Moved FD-macros to
iselect.h. Implement Scheme level `select' using
scm_internal_select. (See NEWS.)
* genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
* init.c: Call scm_init_iselect.
