NAME¶
PAPI_register_thread - Notify PAPI that a thread has 'appeared'.SYNOPSIS¶
Detailed Description¶
C Interface:#include <papi.h>
int PAPI_register_thread (void);
PAPI_register_thread() should be called when the user wants to force PAPI
to initialize a thread that PAPI has not seen before.
Usually this is not necessary as PAPI implicitly detects the thread when an
eventset is created or other thread local PAPI functions are called. However,
it can be useful for debugging and performance enhancements in the run-time
systems of performance tools.
Return values:
PAPI_ENOMEM Space could not be allocated to store
the new thread information.
PAPI_ESYS A system or C library call failed inside PAPI, see the errno
variable.
PAPI_ECMP Hardware counters for this thread could not be
initialized.
