CountAppFiles

CountAppFiles Count selected files; determine Open or Print

#include <SegLoad.h> Segment Loader

void CountAppFiles(doWhat, fileCnt );

 short *doWhat ;  receives action code: 0=open, 1=print
 short *fileCnt ;  receives number of files to  process

Call CountAppFiles to determine how many files the user had selected in the

Finder. This is the first step in determining which file or files the user wants

you to process and what the user wants you to do with it (them).

doWhat is the address of a short. Upon return, it contains one of the

following action codes ( defined in SegmentLdr.h):

appOpen 0 Open the file(s)
appPrint 1 Print the file(s)

fileCnt is the address of a short. Upon return, it contains the number of

files the user selected in the Finder before selecting Open or Print.

If the user double-clicked a document, fileCnt will return containing

a 1.

Notes: After initializing the various managers, most applications will want to

follow these steps to determine what files the user wishes to open or print:

• Call CountAppFiles. If fileCnt =0, open a blank, un titled document.

Otherwise...

• Call GetAppFiles indexing from 1 through fileCnt. Use the returned

information to open or print each file. If you can't or don't want to process

the file, issue a CautionAlert.

• After opening or printing the file, call ClrAppFiles with the same index.

This system lets a user open one or more documents automatically.

Example

#include <SegLoad.h>

#include

short fileCnt, doWhat, index;

AppFile fileStuff;

char *cp = (char *)&fileStuff.ftype; /* ease handling of file type */

CountAppFiles( &doWhat, &fileCnt );

for (index = 1; index <= fileCnt; index++ ) {

GetAppFiles( index, &fileStuff );

/* --- normally you'd open or print the file here ---

PtoCstr( fileStuff.fName ); [TOKEN:12074] convert p-string for printf */

printf("Index: %d, Type: '%c%c%c%c'; name: '%s' \n",

index, cp[0],cp[1],cp[2],cp[3], fileStuff.fName );
