/*
|
|
Routine to get a field from an INF file and convert to an integer. The reason
|
|
we have this and don't use Setupapi!SetupGetIntField is because intl.inf mixes and matches
|
|
numeric conventions. It may use Hex values without a 0x notation and this is an attempt
|
|
to clean that up without modifying the INF. With this change we also won't link to internal Setupapi routines
|
|
like pSetupGetField.

|
Arguments:
|
|
|
|
PINFCONTEXT : - Pointer to setupapi INFCONTEXT structure
|
|
FieldIndex : - 1-based index for fields, 0 for key itself.
|
|
IntegerValue : - Converted Integer value that is returned by the function
|
|
Base : - Base used for string to integer conversion.
|
|
|
|
Return Value:
|

|
TRUE - If we could convert the returned string to an integer else,

FALSE
