@ -238,32 +238,6 @@ coop_condition_variable_init. They will change.
Use scm_mutex_init and scm_cond_init instead.
** scm_mutex_init now takes a second argument
scm_mutex_init has changed: It now takes a second, attribute,
argument. For now, pass NULL as second arg.
If your application uses mutecis and you want to be compatible with
both older and newer Guile's, put:
AC_CACHE_CHECK(for two argument scm_mutex_init,
ac_cv_func_scm_mutex_init_two_args,
AC_TRY_COMPILE([#include <libguile.h>],[scm_mutex_init (NULL, NULL);],
ac_cv_func_scm_mutex_init_two_args=yes,
ac_cv_func_scm_mutex_init_two_args=no))
if test "$ac_cv_func_scm_mutex_init_two_args" = "yes"; then
AC_DEFINE(SCM_MUTEX_INIT_TWO_ARGS, 1,
[define if scm_mutex_init takes two arguments])
fi
in your configure.in and call scm_mutex_init like this:
#ifdef SCM_MUTEX_INIT_TWO_ARGS
scm_mutex_init (&my_mutex, NULL);
#else
scm_mutex_init (&my_mutex);
#endif
** New function: int scm_cond_timedwait (scm_cond_t *COND, scm_mutex_t *MUTEX, const struct timespec *ABSTIME)
`scm_cond_timedwait' atomically unlocks MUTEX and waits on
COND, as `scm_cond_wait' does, but it also bounds the duration
