AESizeOfNthItem

Descriptor type of descriptor record in descriptor list

#include <AppleEvents.h> Apple Event Manager

OSErr AESizeOfNthItem( theAEDescList, index, typeCode, dataSize );

AEDescList * theAEDescList ; descriptor list containing descriptor record

long index ; position of record in the list

DescType * typeCode ; descriptor type of descriptor record

Size * dataSize ; points to size of descriptor record

returns Error Code; 0 = no error

The AESizeOfNthItem function returns the size and descriptor type of a

descriptor record in a descriptor list.

The parameter theAEDescList is the descriptor list containing the

descriptor record.

The index parameter is the position of the descriptor record in the list (for

example, 2 specifies the second descriptor record).

The AESizeOfNthItem function returns the descriptor type of the

descriptor record in the typeCode parameter.

This function returns the length, in bytes, of the data contained in the

descriptor record in the dataSize parameter.
