PAPI_lock() Grabs access to one of the two PAPI mutex variables. This function is provided to the user to have a platform independent call to (hopefully) efficiently implemented mutex.

PAPI_unlock() unlocks the mutex acquired by a call to PAPI_lock.

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

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