PROTOTYPE
unitptr time_unit( char *pcOpt, unitptr uHost)
ARGUMENTS
- char *pcOpt
- option string (unused)
- unitptr uHost
- host unit
RETURN VALUE:
A pointer to the created unit or NULL in the case of an error.
INTERFACE OF CREATED UNIT:
- X_in[0]:
- (input field 0) reference time t0
- X_out[]:
- (output field 0) difference time t-t0
EXECUTION OF CREATED UNIT:
Yields CPU time in seconds since the process was started minus a
reference value that can be given at
the input field (this feature is present to facilitate
the measuring of time differences).
