SYNOPSIS


.In 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.
