GetIndType

You can call the GetIndType procedure repeatedly to get all the resource types available in all resource forks open to your application.

PROCEDURE GetIndType (VAR theType: ResType; index: Integer);

theType

GetIndType returns, in this parameter, the resource type for the specified index among all the resource forks open to your application.

index

An integer ranging from 1 to the number of resource types in all resource forks open to your application.

DESCRIPTION

Given an index number from 1 to the number of resource types in all resource forks open to your application (as returned by CountTypes), the GetIndType procedure returns a resource type in the parameter theType. You can call GetIndType repeatedly over the entire range of the index to get all the resource types available in all resource forks open to your application. If the given index isn't in the range from 1 to the number of resource types as returned by CountTypes, GetIndType returns four null characters (ASCII code 0).

SPECIAL CONSIDERATIONS

The GetIndType procedure may move or purge memory blocks in the application heap. Your application should not call this procedure at interrupt time.

RESULT CODE

noErr

0

No error
