The `Posix` structure

This optional structure contains several substructures that are useful for interfacing to POSIX operating systems. For more complete information on the semantics of the types and functions provided in Posix, see the POSIX standard document (IEEE 1003.1b-1993).

Synopsis

signature POSIX structure Posix : POSIX

Interface

structure Error : POSIX_ERROR structure Signal : POSIX_SIGNAL structure Process : POSIX_PROCESS structure ProcEnv : POSIX_PROC_ENV structure FileSys : POSIX_FILE_SYS structure IO : POSIX_IO structure SysDB : POSIX_SYS_DB structure TTY : POSIX_TTY

Description

structure Error: Errors and their descriptions.
structure Signal: Signal values and their associated numbers.
structure Process: Processes: fork, exec, wait, exit, kill, alarm, pause, sleep.
structure ProcEnv: User and group ID's, process times, environment, etc.
structure FileSys: File system: open, chdir, chmod, directories, etc.
structure IO: Input/output: read, write, pipe, dup, close, lock, seek, sync, etc.
structure SysDB: Password database, group database, etc.
structure TTY: Teletype (TTY) control: speed, attributes, drain, flush, etc.

Discussion

Question:

How can we use SGML to move the TTY comment next to its spec? Maybe by attaching the SHARING constraints to the SIGBODY.

Question:

There are various values allowed in C header files and/or are specified by Posix as compile-time constants, e.g., POSIX_VERSION, POSIX_TIMERS, etc. Should we support these?
