This vector allocates space on the maths stack at BV_RIP(A6).
| Call Parameters | Return Parameters | ||
|---|---|---|---|
| D0.L | Unused | D0.L | Error code SMSQ - Corrupted QDOS. |
| D1.L | Number of bytes required. | D1.L | Corrupted. |
| D2.L | Unused | D2.L | Corrupted. |
| D3.L | Unused | D3.L | Corrupted. |
| A1.L | Pointer to maths stack | A1.L | Corrupted. |
| A6.L | SupBASIC pointer | A6.L | May be changed. |
Errors
No errors QDOS. But for SMSQ -
| ERR_OM | Out of memory. |
Notes
- All registers not shown above are not used on entry and are preserved on exit.
- It is not necessary to allocate space for the routines such as CA_GTINT which fetch parameters for machine code procedures and functions.
Example
The example below shows the use of this vector to allocate space on the maths stack.
Get_space movea.w BV_CHRIX,A2 ; BV_CHRIX vector address.
moveq #16,d1 ; Number of bytes required.
jsr (a2) ; Make the call
bne.s Error_handler ; Oops! (SMSQ only)
