}

; This is in enumerate_sys_apps proc.
; It loops over an array of system application data structs
; and calls a callback for each of them.
; We want it to skip some app idents.
; (ident is the first field of app info, and is negative for sys apps)
; Struct size is 0x24.
;
; There are 4 other funcs which also use that sys apps list,
; but they only search it for certain ident or uuid,
; and not enumerate it all.
