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.
