# The plan9 package provides access to the raw system call

|

# a new architecture/operating system combination requires

# some manual effort, though there are tools that automate

# much of the process. The auto-generated files have names
|

# beginning with z.

# * asm_${GOOS}_${GOARCH}.s
|

#
|
||||
# This hand-written assembly file implements system call dispatch.
|
||||
# There are three entry points:
|
||||
#
|
||||
# func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
|
||||
# func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr);
|
||||
# func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
|
||||
#
|
||||
# The first and second are the standard ones; they differ only in
|
||||
# how many arguments can be passed to the kernel.
|
||||
# The third is for low-level use by the ForkExec wrapper;
|
||||
# unlike the first two, it does not call into the scheduler to
|
||||
# let it know that a system call is running.
|
||||
#
|
||||
# * syscall_${GOOS}.go
|
||||
#
|
||||
# This hand-written Go file implements system calls that need
|
||||
# special handling and lists "//sys" comments giving prototypes
|
||||
# for ones that can be auto-generated. Mksyscall reads those
|
||||
# comments to generate the stubs.
|
||||
#
|
||||
# * syscall_${GOOS}_${GOARCH}.go
|
||||
#
|
||||
# Same as syscall_${GOOS}.go except that it contains code specific
|
||||
# to ${GOOS} on one particular architecture.
|
||||
#
|
||||
# * types_${GOOS}.c
|
||||
#
|
||||
# This hand-written C file includes standard C headers and then
|
||||
# creates typedef or enum names beginning with a dollar sign
|
||||
# (use of $ in variable names is a gcc extension). The hardest
|
||||
# part about preparing this file is figuring out which headers to
|
||||
# include and which symbols need to be #defined to get the
|
||||
# actual data structures that pass through to the kernel system calls.
|
||||
# Some C libraries present alternate versions for binary compatibility
|
||||
# and translate them on the way in and out of system calls, but
|
||||
# there is almost always a #define that can get the real ones.
|
||||
# See types_darwin.c and types_linux.c for examples.
|
||||
#
|
||||
# * zerror_${GOOS}_${GOARCH}.go
|
||||
#
|
||||
# This machine-generated file defines the system's error numbers,
|
||||
# error strings, and signal numbers. The generator is "mkerrors.sh".
|
||||
# Usually no arguments are needed, but mkerrors.sh will pass its
|
||||
# arguments on to godefs.
