OS_Write0
(SWI &02)
| Entry | |
|---|---|
| R0 | Pointer to null-terminated string |
| Exit | |
|---|---|
| R0 | Pointer to the byte after the null |
Use
The purpose of this call is to send a string pointed to by R0 to all active output streams.
Notes
If WrchV vector 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.
An output stream can be specified by using OS_Byte 3.
