#include <stdinc.h>double cputime(void);double cputime2(int mode)float etime(float *tarray);float dtime(float *tarray);
Two old FORTRAN routines, etime and dtime can be compiled into this code, if not available on the local system (-DETIME):
etime returns the elapsed runtime in seconds for the calling process.
dtime returns the elapsed time since the last call to dtime, or the start of execution on the first call. The returned argument tarray contains user time in the first element and system time in the second element. Elapsed time, the returned value, is the sum of user and system time.
28-aug-2012 finally documented PJT 11-jul-2020 added cputime2(mode) PJT
