Subject:	Does IOC name have any restrictions ?

Hello,

I am getting a make error in ioc generation using makeBaseApp, if I use any numeric in name "test".

I created IOC using this,

../bin/windows-x64-mingw/makeBaseApp.pl -t ioc 3test

../bin/windows-x64-mingw/makeBaseApp.pl -i -t ioc 3test

But, make fails with following error.

----------------

3test_registerRecordDeviceDriver.cpp:248:5: error: expected unqualified-id before numeric constant

248 | int 3test_registerRecordDeviceDriver(DBBASE *pbase)

| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3test_registerRecordDeviceDriver.cpp: In function 'void rrddCallFunc(const iocshArgBuf*)':

3test_registerRecordDeviceDriver.cpp:291:19: error: unable to find numeric literal operator 'operator""test_registerRecordDeviceDriver'

291 | iocshSetError(3test_registerRecordDeviceDriver(*iocshPpdbbase));

-------------------------

It works fine if i use non-numeric, say using 'rtest' instead of '3test' is working fine. I am working on Windows 10 and MSYS environment.

Do we have any restriction in naming convention for IOC? or this is something else ?

Regards,
Hitesh
