OS_WriteN
(SWI &46)
| Entry | |
|---|---|
| R0 | Pointer to string |
| R1 | Number of bytes to write |
| Exit | |
|---|---|
| R0 | Preserved |
| R1 | Preserved |
Use
The purpose of this call is to write a counted string to the VDU.
Notes
This SWI sends the R1 bytes in R0 to all active output streams (specified by OS_Byte 3).
If WrchV has not been intercepted with OS_Claim it will directly call the VDU driver which is faster, otherwise it calls OS_WriteC to write each character.
