NAME
     colldef --	convert	collation sequence source definition

SYNOPSIS
     colldef [-I map_dir] [-o out_file]	[filename]

DESCRIPTION
     The colldef utility converts a collation sequence source definition into
     a format usable by	the strxfrm() and strcoll() functions.	It is used to
     define the	many ways in which strings can be ordered and collated.
     strxfrm() transforms its first argument and places	the result in its sec-
     ond argument.  The	transformed string is such that	it can be correctly
     ordered with other	transformed strings by using strcmp(), strncmp(), or
     memcmp().	strcoll() transforms its arguments and does a comparison.

     The colldef utility reads the collation sequence source definition	from
     the standard input	and stores the converted definition in filename.  The
     output file produced contains the database	with collating sequence	infor-
     mation in a form usable by	system commands	and routines.

     Options list:

     -I	map_dir
	   This	option set directory name where	charmap	files can be found,
	   current directory by	default.

     -o	out_file
	   This	option set output file name, LC_COLLATE	by default.

     The collation sequence definition specifies a set of collating elements
     and the rules defining how	strings	containing these should	be ordered.
     This is most useful for different language	definitions.

     The specification file can	consist	of three statements: charmap,
     substitute	and order.

     Of	these, only the	order statement	is required.  When charmap or
     substitute	is supplied, these statements must be ordered as above.	 Any
     statements	after the order	statement are ignored.

     Lines in the specification	file beginning with a #	are treated as com-
     ments and are ignored.  Blank lines are also ignored.

     charmap charmapfile

     charmap defines where a mapping of	the character and collating element
     symbols to	the actual character encoding can be found.

     The format	of charmapfile is shown	below.	Symbol names are separated
     from their	values by TAB or SPACE characters. symbol-value	can be speci-
     fied in a hexadecimal (\x??) or octal (\???)  representation, and can be
     only one character	in length.

     symbol-name1 symbol-value1
     symbol-name2 symbol-value2
     ...

     The charmap statement is optional.

     substitute	symbol with "repl_string"

     The substitute statement substitutes the character	symbol with the	string
     repl_string.  Symbol names	cannot be specified in repl_string field.  The
     substitute	statement is optional.

     order order_list

     order_list	is a list of symbols, separated	by semi	colons,	that defines
     the collating sequence.  The special symbol ... specifies,	in a short-
     hand form,	symbols	that are sequential in machine code order.

     An	order list element can be represented in any one of the	following
     ways:

     +o	 The symbol itself (for	example, a for the lower-case letter a)

     +o	 The symbol in octal representation (for example, \141 for the letter
	 a)

     +o	 The symbol in hexadecimal representation (for example,	\x61 for the
	 letter	a)

     +o	 The symbol name as defined in the charmap file	(for example,
	 _letterA_ for letterA \023 record in charmapfile).  If	character map
	 name have _ character,	it must	be escaped as /_, single / must	be es-
	 caped as //.

     +o	 Symbols \a, \b, \f, \n, \r, \v	are permitted in its usual C-language
	 meaning

     +o	 The symbol chain (for example:	abc, _letterA__letterB_c, \xf1b\xf2)

     +o	 The symbol range (for example,	a;...;z)

     +o	 Comma-separated symbols, ranges and chains enclosed in	parenthesis
	 (for example (	sym1, sym2, ...	)) are assigned	the same primary or-
	 dering	but different secondary	ordering.

     +o	 Comma-separated symbols, ranges and chains enclosed in	curly brackets
	 (for example {	sym1, sym2, ...	}) are assigned	the same primary or-
	 dering	only.

     The backslash character \ is used for continuation.  In this case,	no
     characters	are permitted after the	backslash character.

DIAGNOSTICS
     The colldef utility exits with the	following values:

     0	     No	errors were found and the output was successfully created.

     !=0     Errors were found.

FILES

					      collation	 orders	under the lo-
					      cale locale
