NAME

       PAPI_get_virt_nsec - Get virtual time counter values in nanoseconds.

SYNOPSIS

Detailed Description

       Return values
           PAPI_ECNFLCT If there is no master event set. This will happen if the library has not
           been initialized, or for threaded applications, if there has been no thread id
           function defined by the PAPI_thread_init function.
           PAPI_ENOMEM For threaded applications, if there has not yet been any thread specific
           master event created for the current thread, and if the allocation of such an event
           set fails, the call will return PAPI_ENOMEM or PAPI_ESYS .

       This function returns the total number of virtual units from some arbitrary starting
       point. Virtual units accrue every time the process is running in user-mode on behalf of
       the process. Like the real time counters, this count is guaranteed to exist on every
       platform PAPI supports. However on some platforms, the resolution can be as bad as 1/Hz as
       defined by the operating system.
