CountResources

CountResources Find how many of a selected resource type exist

#include <Resources.h> Resource Manager

short CountResources(rType );

ResType rType ; a 4-byte ResType; the resource type to count

returns total rType resources in all open resource files

CountResources returns the number of resources of a specified resource

type that exist among the currently-open resource files.

rType is a 4-byte ResType value identifying the resource type you wish to

count (e.g. 'FONT', 'MENU', etc.).

Returns: a positive integer; the number of resources of the specified type

contained in all currently-open resource files. Returns 0 if none are

found.

Notes: This function is used as the first step in generating a list of

currently-available resources of a particular type. To generate the list,

use GetIndResource with an index ranging from 1 to the

CountResources return value.

Use Count1Types and Get1IndResource to count and access only the

resources in the current resource file.

The following example prints a list of the names of all resources of type

'DRVR' (i.e., desk accessories).

Example

#include <Resources.h>

short rCount, rID, j;

Handle rHandle;

printf("\n"); [TOKEN:12074] ensure printf can get fonts */

/* before calling SetResLoad */

rCount = CountResources( 'DRVR' );

SetResLoad( FALSE ); [TOKEN:12074] do not need resource, just info */

for( j=1; j <= rCount; j++ ) {

rHandle = GetIndResource('DRVR', j );

GetResInfo( rHandle, &rID, &rType, rName );

printf(" 'DRVR' Rsrc ID: %6d, Name: %s\n", rID, PtoCstr(rName)+1);

}

SetResLoad(TRUE); [TOKEN:12074] better do this! */
