Typedef Documentation

◆ MemoryMap_t

typedef std::map<std::string, int64_t> MemoryMap_t

Definition at line 30 of file PerfMonMTUtils.h.

Function Documentation

◆ ATLAS_NOT_THREAD_SAFE()

double PMonMT::get_malloc_kb ATLAS_NOT_THREAD_SAFE ( )

inline

Install fatal handler with default options.

This is meant to be easy to call from python via ctypes.
