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 a (hopefully) efficiently implemented mutex.
CInterface:
#include <papi.h>
void PAPI_lock(intlock);
Parameterslock -- an integer value specifying one of the two user locks: PAPI_USR1_LOCK or PAPI_USR2_LOCK
Returns
There is no return value for this call. Upon return from PAPI_lock the current thread has acquired
exclusive access to the specified PAPI mutex.
