Description
This section describes the manual page on which each kernel
routine is found.
The following table summarizes the kernel routines. The
columns indicate the routine name, the manual page on which
the routine appears, a description, and a code that
indicates the following values:
_______________________________________________________________
| Letter| Meaning |
|_______|______________________________________________________|
| B | Use this routine only in a block driver |
| C | Use this routine only in a character driver |
| G | General; can be used in a block or character driver |
| I | Routine can be called from an initialization routine|
| X | Routine can be called from an interrupt routine |
| M | Macro |
| A | Written in Assembly language |
