=> R0 = structure specifier
R1 = pointer to bad block list (terminated by -1)
R2 = pointer to null terminated disc name
R3 = image file handle
<= R0-R3 preserved
This call lays out in the specified image all necessary structures to have a valid, empty disc. It can be used:
· to layout a structure on a blank, formatted disc (in which case the specified image should be the whole disc image)
· to layout a partition in a file on a disc that has already been formatted (for example for the PC emulator).
If the given image format has no option to store a disc name then this parameter will be ignored.
The bad block list should be presented as an array of bad block addresses. Each address is 4 bytes long. The array is terminated by a -1 entry.
It's assumed that R0 gives enough information for the format - other filing systems may use it to pass bit fields or pointers to more complex structures. However, DOSFS uses a simple table index for this.
Under RISC OS 3.00 this SWI erroneously had the SWI number &41AC1, do not support this in your code.
See PRM 2, page 332.
