View Ref-File[ Resource File Extension ]

typedef struct
 {
  long full_size;         /* actual size of resource file (bytes) */
  long rsx_cicon;         /* offset to CICONBLK* array            */
  long rsx_term;          /* 0L                                   */
 } RSEXT;

Actually, the CICONBLK array contains NULLs in the resource file,
and is filled when the resource file is loaded into memory.  The array
is terminated with a entry containing -1L.

Immediately following this array is the first color icon definition:

CICONBLK icon;            /* pointers not filled               */
int mono_data[?];         /* standard icon image               */
int mono_mask[?];         /* standard mask image               */
char icon_text[12];       /* icon text field                   */

For each supported resolution there follows:

CICON res;                /* pointers not filled               */
int color_data[?];        /* VDI device independent image      */
int color_mask[?];        /* single bit plane image            */
int select_data[?];       /* VDI device independent image      */
int select_mask[?];       /* single bit plane image            */

Some of the pointers in the above structure contain other information:
icon.mainlist contains the number of resolutions supported.
res.sel_data == 0 when there is no separate "selected" image.
res.next_res == 1 when there are more icons following.

After the last resolution, the sequence repeats for the next icon.

Implemented starting with AES Version 3.30 (rsh_vrsn = 4).
