Argument structure used for getting and setting widget resources
typedef struct Pt_arg_entry {
long type;
long value;
long len;
} PtArg_t;
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.
