The Resource Type
The Resource Manager uses the resource type along with the resource ID to identify a resource uniquely. A resource type is defined by theResTypedata type.
TYPE ResType = PACKED ARRAY[1..4] OF Char;A resource type can be any sequence of four alphanumeric characters, including the space character. You can define your own resource types, but they must consist of all uppercase letters and must not conflict with any of the standard resource types.
Table 1-2 lists the standard resource types.
- IMPORTANT
- When identifying resource types, the Resource Manager distinguishes between uppercase letters and their lowercase counterparts. In addition, Apple reserves for its own use all resource types that consist of all lowercase letters, all spaces, or all international characters (characters greater than $7F).
Table 1-3 lists resource types that are reserved for use by system software. These resource types consist entirely of uppercase letters or combinations of uppercase and lowercase letters and the number sign (#). Other resource types specific to system software that consist entirely of lowercase letters or other characters are not included in Table 1-3. This list is provided for your information; you should not use these resource types in your application.
