These are minor fixes I've accumulated over time. The following
changes are somewhat notable:
- Added a missing entry for 'typeset -s' to the man page.
- Add strftime(3) to the 'see also' section. This and the date(1)
addition are meant to add onto the documentation for 'printf %T'.
- Removed the man page the entry for ksh reading $PWD/.profile on
login. That feature was removed in commit aa7713c2.
- Added date(1) to the 'see also' section of the man page.
- Note that the 'hash' command can be used instead of 'alias -t' to
workaround one of the caveats listed in the man page.
- Use an 'out of memory' error message rather than 'out of space'
when memory allocation fails.
- Replaced backticks with quotes in some places for consistency.
- Added missing documentation for the %P date format.
- Added missing documentation for the printf %Q and %p formats
(backported from ksh2020: https://github.com/att/ast/pull/1032).
- The comments that show each builtin's options have been updated.

The advanced software technology department has been collecting useful C
|
|
routines in a single library called libast. libast is used by nmake, the
|
|
nmake cpp (which is mainly based on another library (libpp)), CIA
|
|
(C information abstractor from Robin Chen), and a collection of other
|
|
/bin and /usr/bin commands that benefit from concentrating functionality
|
|
in libast.
|
|
|
|
More detail is available in the man pages. libast contains:
|
|
|
|
(1) routines to support a generic environment for
|
|
a variety of UNIX operating system variants
|
|
|
|
(2) routines that update standard libc routines
|
|
|
|
(3) routines shared between several commands
|
|
|
|
If you already have nmake 2.0 or newer installed then use
|
|
`nmake install' from this directory, otherwise use
|
|
ship/shipin from the root of the distribution directory tree.
|
|
|
|
Some of the routines not found in section 3:
|
|
|
|
hash: generic, scoped hash table support
|
|
|
|
hashalloc create a hash table or push new scope
|
|
hashdump debug dump of one or all hash tables
|
|
hashfree free a hashalloc()'d table
|
|
hashlook low level name lookup
|
|
hashscan entry generator for scoped table scan
|
|
hashsize explicitly change table size (usually automatic)
|
|
hashwalk apply function to each table entry
|
|
memhash return hash code for n-char chunk of memory
|
|
strhash return hash code for null-terminated string
|
|
|
|
include/ast: libast support headers
|
|
|
|
align.h compile time type alignment support
|
|
dirent.h POSIX directory(3) interface definitions
|
|
error.h error() interface definitions
|
|
ftw.h ftwalk() interface definitions
|
|
hash.h hash*() interface definitions
|
|
ls.h strls() interface definitions
|
|
re.h re*() interface definitions
|
|
tar.h POSIX ustar format interface definitions
|
|
tm.h tm*() interface definitions
|
|
|
|
misc:
|
|
|
|
cmdargs apply a sequence of cmd line option parsers
|
|
cmdopen like popen() but stdin and stdout are specified
|
|
cvtatoe convert ASCII to EBCDIC
|
|
cvtetoa convert EBCDIC to ASCII
|
|
error output generic error and trace messages
|
|
ftwalk an ftw(3) that works -- used in new tw(1)
|
|
getcwd uses $PWD if ok, doesn't use /bin/pwd
|
|
getshell return full path of shell for cmdopen()
|
|
ooptget optget() for obsolete ar(1) and tar(1) options
|
|

|
|

|
|
pathcanon canonicalize path name in place
|
|
pathcmd return full path name of executable using $PATH
|
|
pathroot determine `related root' directory for command
|
|
perror uses strerror()
|
|
readargs append each line of file to argv[0]
|
|
|
|
re: egrep(1) and ed(1) style re's from V9
|
|
(not the good awk(1) algorithm)
|
|
|
|
recomp compile re pattern
|
|
reerror report re*() errors
|
|
reexec match string using compiled re
|
|
resub ed(1) style substitute using last reexec()
|
|
|
|
string:
|
|
|
|
chresc return next char in string converting \ sequences
|
|
ctoi convert char constant string to int
|
|
strcopy like strcpy(3) but returns end of destination
|
|

|
|
strerror return error message string given errno

|
|

|
|

|
|
|

|
|
tmmake return current time_t
