DESCRIPTION

22       PAPI_lock()  Grabs  access to one of the two PAPI mutex variables. This
23       function is provided to the user to have a platform independent call to
24       (hopefully) efficiently implemented mutex.
25
26       PAPI_unlock() unlocks the mutex acquired by a call to PAPI_lock.

ARGUMENT

30       lock  --   an  integer  value  specifying  one  of  the two user locks:
31       PAPI_USR1_LOCK or PAPI_USR2_LOCK
32
33

RETURN VALUES

35       There are no return values for these calls. Upon return from  PAPI_lock
36       the  current thread has acquired exclusive access to the specified PAPI
37       mutex.
