Routine Description:
|

|
|
Looks for indices and refresh rate arguments in the command. If index

|
tag is present, it would be of the form index= index1 index2 ....
|
||
|
|
The index= is removed by this function. So is rr= if it is there in
|
||
|
|
the command. If pdwRR is 0 then, no refresh sought.

|
Arguments:
|
||
|
|
|
||
|
|
pptcArguments - The argument array. Each argument has tag=value form
|
||
|
|
dwCurrentIndex - pptcArguments[dwCurrentIndex] is first arg.
|
||
|
|
dwArgCount - pptcArguments[dwArgCount - 1] is last arg.
|
||
|
|
pttTagToken - Array of tag token ids that are allowed in the args
|
||
|
|
dwNumTags - Size of pttTagToken
|
||
|
|
pdwOut - Array identifying the type of each argument.
