source: vbox/trunk/src/VBox/Runtime/testcase/tstStrToNum.cpp@ 67457

Last change on this file since 67457 was 62723, checked in by vboxsync, 8 years ago

RTDirCreateUniqueNumbered: Changed the implementation to count from zero and only do 20 sequential tries before switching to random numbers. Also, don't bother retrying more than 10000 times. Corrected the cchDigits parameter (nobody counts in signed int!).
