3.22.2.6 struct x1f4_eelookup_type

typedef struct x1f4_eelookup_type {
    struct {
        int (*fix)(const void *, int, const char **, unsigned *);
        const void *context;
    } type_l;
    struct {
	const void *e4fine;
    } type_q;
} x1f4_eelookup_type;

The struct x1f4_eelookup_type record describes name lookup means. It is used for error reports creation, but also for some non error reporting purposes.

See Error Reporting.

See x1f4_stat_expression.

type_l

and:

type_q

specify the means to retrieve the names of the application defined data types as:

fix

the type name look up method

context

the type name look up context

e4fine

the function pointer symbolic to logical type mapper

See Function Pointers.

See Function Pointer Type Alloter.

Whenever the name of an application defined data type needs to be looked up the type name look up method is called with the type name look up context as its first argument and the type id as its second argument. The name look up method is expected to return 0 for success, non zero for failure. In the former case the string and cardinal records pointed to by the third and fourth method arguments are expected to be set to the type name and its length.

The type name lookup is attempted via the type name lookup method for all application data types, including function pointer data types.

When the fix type name lookup method fails the name lookup and the symbolic type (the type id) is a function pointer type and e4fine is set (not NULL) the type name lookup is attempted against the function type mapper.

If fix is NULL no type name lookup is attempted.
