Re: GS/OS: looking for info on VCB and FCB

[Toinet <antoine.vignau@laposte.net>]

There are a few other calls that are not documented on the GS/OS
Device Driver Reference book (I have documented some of them above) :

- DEV_DISPATCHER ($01FC00)
- CACHE_INIT ($01FC0C)
- CACHE_SHUTDOWN ($01FC10)
- ALLOC_VCR ($01FC24)
- RELEASE_VCR ($01FC28)
- ALLOC_FCR ($01FC2C)
- RELEASE_FCR ($01FC30)
- GET_SYS_GBUF ($01FC3C)
- SYS_EXIT ($01FC40)
- SYS_DEATH ($01FC44)
- FIND_VCR ($01FC48)
- FIND_FCR ($01FC4C)
- CACHE_LOCK ($01FC54)
- RENAME_VCR ($01FC58)
- RENAME_FCR ($01FC5C)
- GET_VCR ($01FC60)
- GET_FCR ($01FC64)
- CVT_0TO1 ($01FC74)
- CVT_1TO0 ($01FC78)
- GET_BOOT_PFX ($01FCAC)
- SET_BOOT_PFX ($01FCB0)

There are other system service calls that remain "unexplained":
- $01FC7C
- $01FC80
- $01FC84
- $01FC8C
- $01FC94
- $01FC98
- $01FC9C
- $01FCA0
- $01FCB4
- $01FCB8
- $01FCC0
- $01FCC4
- $01FCC8
- $01FCCC
- $01FCD0
- $01FCD4
- $01FCDC
- $01FCE0

There are structures that have not been documented either:
- Volume Control Record
- File Control Record
The goal of the structures is to keep information on volumes and files
for the FSTs and GS/OS. The structure is not similar to the same ones
described on Inside Mac volume 4.

Any help would be appreciated. I have asked the same info to someone
who is/has been close to Apple. Wait & see...
