\ syscalls.4th
\
\ Selected system calls for kForth ver >= 1.5.x on Linux.
\
\ !!! see WARNING below !!!
\
\ Copyright (c) 2004--2021 Krishna Myneni,
\ Provided under the GNU General Public License
\
\ Notes:
\
\ 0) WARNING: Not all system calls provided here as Forth words have been
\ tested. USE WITH CAUTION -- it may be possible to DAMAGE
\ YOUR SYSTEM due to bugs in this code, or with improper
\ arguments to a syscall word. The appropriate arguments for
\ a particular system call are documented in the Linux man
\ page, section 2, for that call. For example, type
\
\ man 2 lseek
\
\ to obtain the man page for the lseek system call.
\ Note the following for the arguments to a word:
\
\ a) addresses to strings must contain a NULL terminated
\ string.
\
\ b) addresses to structures must contain data packed with
\ the correct alignment for that structure.
\
\ 1) System calls under Linux may also be performed using a software
\ interrupt, $80, and placing the parameters in appropriate
\ registers.
\
\ 2) There are over 300 system calls under Linux. A number of
\ these are provided in the form of Forth words here. System call
\ numbers may be found in /usr/include/asm/unistd_32.h
\
\ 3) The words OPEN, CLOSE, READ, WRITE, LSEEK, and IOCTL are already
\ defined in kForth with the same behavior.
\
\ Revisions:
\ 2004-09-16 created KM
\ 2005-11-07 ported to kForth (requires asm-x86.4th) KM
\ 2009-09-26 the word SYSCALL has been intrinsic to kForth
\ since v. 1.4.1; this file is now updated
\ to use the intrinsic SYSCALL and no longer requires
\ asm-x86.4th; KM
\ 2010-04-17 renamed this file from syscalls386.4th to
\ syscalls.4th; KM
\ 2010-04-29 added numerous syscalls; most have NOT been tested KM
\ 2010-04-30 renamed open to sys_open; revised comments KM
\ 2012-01-25 made syscalls a module km
\ 2012-01-27 fixed stack diagram for getcwd; mmap with 6 args
\ needs to use syscall 90 with 1 structure arg KM
\ 2015-08-01 added MAP_ANONYMOUS km
\ 2019-12-29 updated for use on both 64-bit and 32-bit systems km
\ 2020-01-30 conditional definition of FSYNC (now intrinsic) km
\ 2021-05-18 added WAITID and associated constants; extended
\ defined syscall numbers for both 32-bit and 64-bit km
\ 2021-06-31 added WAITPID for 64-bit system km
