RxUptime - get system uptime information

RxUptime is an OS/2 Warp REXX extension DLL for getting system uptime information from DosQuerySysInfo() and DosTmrQueryFreq()/DosTmrQueryTime().

The DLL exports the functions

RxLoadUptime

Load all uptime functions
RxDropUptime
Drop all uptime functions.
RxMSCount
Query running millisecond count via DosQuerySysInfo(). Returns the number of milliseconds, or -1 if there was an error during execution.
RxTmrFreq
Query CPU timer frequency via DosTmrQueryFreq(). Returns the number of Hertz, or -1 if there was an error.
RxTmrTime
Query CPU timer count via DosTmrQueryTime(). Returns the number of cycles, or -1 if there was an error.

Hint from the author:

"All functions take no arguments. I seem to recall reading somewhere that the DosTmr*() API's were added with Warp 4, so functionality under Warp 3 is indeterminate."
