; Defines the platform-specific error list.
;
; The table is built as a list of entries:
;
;       .byte   entrylen
;       .byte   errorcode
;       .asciiz errormsg
;
; and, terminated by an entry with length zero that is returned if the
; error code could not be found.
;

.export __sys_oserrlist

.include "rp6502.inc"
.include "errno.inc"

;----------------------------------------------------------------------------
; Macros used to generate the list (may get moved to an include file?)

; Regular entry
.macro sys_oserr_entry code, msg
    .local Start, End
Start:
    .byte End - Start
    .byte code
    .asciiz msg
End:
.endmacro

; Sentinel entry
.macro sys_oserr_sentinel msg
    .byte 0  ; Length is always zero
    .byte 0  ; Code is unused
    .asciiz msg
.endmacro
