the requested number of preferences. On output, itemCount

prefsTOC parameter must have enough CfgPrefsHeader
structures to store all of the preferences in the entity.
function result A value of noErr indicates that OTCfgGetPrefsTOC returned

DISCUSSION
The OTCfgGetPrefsTOC function obtains information about the specified number
preferences in the entity represented by accessID and stores them in the
prefsTOC array.
Before you call OTCfgPrefsTOC, you must should find out how many preferences
are available by calling OTCfgGetPrefsTOCCount (page 88).

WARNING
Early versions of Network Setup do not determine whether
there is enough space in prefsTOC (as specified on input by
itemCount) and can write beyond the end of the array. You
should always call OTCfgGetPrefsTOCCount before calling
OTCfgGetPrefsTOC. When you call OTCfgGetPrefsTOC, set
itemCount to the value returned by OTCfgGetPrefsTOCCount
in the
itemCount parameter. ▲
