NAME

     CK_COHORT_TRYLOCK — try to acquire cohort lock

LIBRARY

     Concurrency Kit (libck, -lck)

SYNOPSIS

     #include <ck_cohort.h>

     CK_COHORT_TRYLOCK(COHORT_NAME cohort_name, COHORT *cohort, void *global_trylock_context,
         void *local_trylock_context, void *lock_unlock_context);

DESCRIPTION

     This call attempts to acquire both the local and global (if necessary) locks from cohort.
     It can only be used with cohort types that were defined using the
     CK_COHORT_TRYLOCK_PROTOTYPE(3) macro.  The call will not block and will return a bool that
     will evaluate to true iff the cohort was successfully acquired.  global_trylock_context will
     be passed as the second argument to the function that was provided as the
     global_trylock_method argument to CK_COHORT_TRYLOCK_PROTOTYPE if that method is called, and
     local_trylock_context will be passed to the function specified by local_trylock_method.  If
     the global lock acquisition fails, then the cohort will immediately release its local lock
     as well, and local_unlock_context will be passed to the function specified by
     local_unlock_method when this call is made.
