Passing in an 'adj' of -1 will get the immediately preceeding source

the last source cue FOR THAT FILE. The cue adjust never crosses a

1 will get the first source cue FOR THAT FILE. If an adjustment
causes a wrap from begining to end or vice versa, you should return

DCStatus be called in this case). Otherwise DS_OK should be returned

Given the imp_type_handle, copy the name of the type into 'buff'.
Do not copy more than 'buff_size' - 1 characters into the buffer and
append a trailing '\0' character. Return the real length
of the type name (not including the trailing '\0' character) even
if you had to truncate it to fit it into the buffer. If something
went wrong and you can't get the type name, call DCStatus and
return zero. NOTE: the client might pass in zero for 'buff_size'. In that
case, just return the length of the module name and do not attempt
to put anything into the buffer.
Since there can be a "string" of typedef names associated with
a type_handle, the 'num' parm indicates which one of the names
the client wants returned. Zero is the first type name, one is
the second, etc. Fill in '*tag' with ST_ENUM_TAG, ST_UNION_TAG,
ST_STRUCT_TAG, ST_CLASS_TAG if the name is a enum, union, struct,
or class tag name respectively. If not, set '*tag' to ST_NONE.
If the type does not have a name, return zero.
