	I want do realize the "Get Info feature" by program e.g I want a
procedure, say GetCatFilesInfo, that gives me the entire size of a specific
catalog, and the number of files and catalogs within this catalog.

	Thus, reading IM..., I must use GetCatInfo(). The body of the procedure
(in C) is :

		OsErr GetCatFilesInfo(TheCInfoPBPtr)
		CInfoPBPtr	TheCInfoPBPtr ;
		{
			do a GetCatInfo(TheCInfoPBPtr) ;
			do a PBOpenWD(&LocalWDPBRec) ;

			for ( i = 1 ; i < TheCInfoPBPtr->dirInfo.ioDrNmFls ; i++ )
			{	working on a local CinfoPBRec, retrieve info for each file
				(using ioFDirIndex and ioDrDirID fields).

				GetCatInfo(&LocalCInfoPBRec) ;

				if ( file is a directory )
				{	call GetCatFilesInfo() ;

					/* THE PROBLEM IS HERE!!!!!! 
					   WHICH FIELDS MUST I USE, IN ORDER TO RETRIEVE
					   RECURSIVELY THE OTHER FILES AND CATALOGS ?
					*/

				}

				retrieve ioFlLgLen and ioFlRlgLen and other stuffs, from
				LocalCInfoPBRec.
			}

			do a PBCloseWD(&LocalWDPBRec) ;
		}


Any information or C source code will be very appreciate.
