27System Call Files
28------ ---- -----
29
30The universal dumping grounds for system calls in Solaris 2.x,
31common/os/scalls.c and common/fs/vncalls.c, have been sub-divided into
32smaller files.
33
34The old files had become quite large, and contained much completely
35unrelated code. From a software engineering standpoint, it didn't seem
36like a good idea to permit system calls or underlying routines
37to be cognizant of the internal interfaces and underlying routines
38of unrelated system calls.
39
40From a practical standpoint, recompiling all of scalls.c or vncalls.c
41after making only a small change in one system call seemed like
42cruel and unusual punishment.  Also, running "bringover" after
43changing scalls.c or vncalls.c in one's own environment had a
44high probability of encountering a conflict.
45
46In an attempt to improve maintainability, we have split these files
47and created new directories to hold the results. One hopes that this
48new organization will prove easier to maintain and change.
49
50The principles listed below guided the split-up. Please try to adhere
51to them if you add new system calls.
52
53
541) System calls now live in directories called "syscall". Architecture
55   independant system calls live in common/syscall and architecture
56   dependant system calls live in sparc/syscall or i86/syscall.
57
582) Most system calls have their own separate file. We try to keep
59   these files as small as possible.
60
613) Unrelated system calls should NEVER be put in the same file. Do
62   not consider any of these files "dumping grounds" for new system
63   call work.
64
654) Some files DO contain more than one system call. This occurs
66   under the following restricted conditions:
67
68	o System calls that are internally related, either because
69	  they alone call a set of static functions to do the dirty
70	  work, or because they access locally-defined static data.
71	  The system calls in sigqueue.c and lwpsys.c are examples
72	  of the first case; lwp_sobj.c is an example of the second.
73
74	o Fairly trivial pairs of "get-" and "set-" operation system
75	  calls. The file rlimit.c, containing getrlimit() and
76	  setrlimit() is a case in point.
77
78	o System calls that are basically "variations on a theme,"
79	  such as the the different forms of stat in stat.c.
80
815) If a number of system calls make use of a local function, or,
82   if a function is used more widely than in a few system calls,
83   then perhaps this function needs to be moved to one of the
84   kernel-implementation files in common/os or common/fs. For
85   example, this was done with the functions namesetattr and
86   fdsetattr, which were used by several different system calls.
87   These functions were moved into common/os/fio.c, where they
88   seemed to fit better.
89
90-------------------------------------------------------------------
91System Call Reorganization
92------ ---- --------------
93
94The system calls in common/os/scalls.c, common/fs/vncalls.c
95have been broken up into smaller files. In addition, system
96calls that previously resided in <arch>/os/archdep.c have
97been removed from that file. The table below describes the
98manner in which the files have been split up.
99
100The original syscall files have not been deleted, but have been
101renamed to reflect their diminished contents. The file scalls.c
102has been renamed to ssig.c, and vncalls.c has been renamed to
103poll.c.

301-----------------------------------------------------------------
302
303Most of the system calls in this directory have been converted
304to use C-style argument passing, instead of the old uap-pointer
305method. This usually makes the system calls faster and more
306"natural" in implementation.
307
