IOB_SUML & IO_SSTRG/IOB_SMUL
These traps send strings of bytes to a channel. IOB_SUML is SMSQ Only.
| Call Parameters | Return Parameters | ||
|---|---|---|---|
| D0.B | $06 or $07 | D0.L | Error code. |
| D1.L | D1.L | Number of bytes sent. | |
| D2.L | Number of bytes to send. | D2.L | Preserved. |
| D3.W | Timeout. | D3.L | Preserved. |
| A0.L | Channel ID. | A0.L | Preserved. |
| A1.L | Pointer to buffer. | A1.L | Pointer to one byte after the last sent. |
Errors
| ERR_NC | Not complete. |
| ERR_NO | Channel not open. |
| ERR_DF | Drive full. |
Notes
- All registers not shown above are not used on entry and are preserved on exit.
- D0.B is $06 for IOB_SUML and $07 for IO_SSTRG/IOB_SMUL.
- IOB_SUML is the same as IO_SSTRG/IOB_SMUL except that there is no translation of the characters.
- If the output is to a CON or SCR channel LF is generated when the character to be printed is at the right hand end of the window.
Example
The example below shows the use of this trap call to print a string to the channel whose ID is in A0.
strg dc.w strg_e-strg-2 ; Length of string
ds.b "This is the string"
strg_e ds.b 0
ds.w 0 ; Set to even byte
print lea strg,a1
move.w (a1)+,d2 ; Number of characters
move.w #-1,d3 ; Timeout
moveq #FS_SSTRG,d0 ; Send (with translation)
tst.l d0 ; OK? . .
bne error ----> ; . . no!
