NAME
pfm_initialize - initialize performance monitoring librarySYNOPSIS
#include <perfmon/pfmlib.h> int pfm_initialize(void);
DESCRIPTION
This is the first function that a program using the library must call otherwise the library will not function at all. This function will probe the host CPU and automatically detect which PMU it has. All internal data structures will be initialized as a result of this call. In the case of a multi-threaded application, this function needs to be called only once, most likely by the initial thread.RETURN
The function returns whether or not it was successful, i.e., the host PMU has been correctly identified and is supported. A return value of PFMLIB_SUCCESS indicates success, otherwise the value is an error code.ERRORS
- PFMLIB_ERR_NOTSUPP
- the host PMU is not supported.
