PtArg_t

Which resource is affected when you get or set resources

Synopsis:

typedef struct Pt_arg_entry {
    long                type;
    long                value;
    long                len;
} PtArg_t;

Description:

You use the PtArg_t structure extensively when dealing with widget resources. It's the first argument in the PtSetArg() macro.

This structure contains at least the following members:

type

The resource type (for example, Pt_ARG_TEXT_STRING) to be set or queried.

value

Either the value to set the resource to or, if you're querying the resource, the address of a pointer.

len

The purpose of this member is determined by the Pt type of the resource.
