Resets Performance Monitor data for a target pthread.
Performance Monitor APIs Library (libpmapi.a)
The pm_reset_data_pthread subroutine resets the current Performance Monitor data for a target pthread. The pthread must be stopped and must be part of a debuggee process. The data is a set (one per hardware counter on the machine used) of 64-bit values. All values are reset to 0.
If the pthread is running in 1:1 mode, only the tid parameter must be specified. If the pthread is running in m:n mode, only the ptid parameter must be specified. If both the ptid and tid parameters are specified, they must be referring to a single pthread with the ptid parameter specified and currently running on a kernel thread with specified tid parameter.
