NAME
       strord - convert string data order

SYNOPSIS
DESCRIPTION
       The  text orientation (mode) of a file can be right-to-left (non-Latin)
       or left-to-right (Latin).  This text orientation	 can  affect  the  way
       data  is	 arranged  in the file.	 The data arrangements that result are
       called screen order and keyboard order.

       converts the order of characters in s2 from screen to keyboard order or
       vice  versa and places the result in s1.	 The arguments s1 and s2 point
       to strings (arrays of  characters  terminated  by  a  null  character).
       returns s1.

       performs	 the  conversion  based	 on  mode information indicated by the
       argument m.  The argument m is of type nl_mode found in the header file
       The mode argument can have two possible values: and

       If  the mode argument is the text orientation is left-to-right, and all
       non-Latin sub-strings are reversed.  Non-Latin sub-strings are any num‐
       ber  of	contiguous  right-to-left language characters.	Non-Latin sub-
       strings are delimited by ASCII characters.

       Similarly, if the mode argument is the text  orientation	 is  right-to-
       left and all Latin sub-strings are reversed.  Latin sub-strings are any
       number of contiguous printable ASCII characters.	 Latin sub-strings are
       delimited by right-to-left language characters and ASCII control codes.

       Some  right-to-left  languages  have  a	duplicate set of digits called
       alternative numbers.  Alternative numbers always have  a	 left-to-right
       orientation.

EXTERNAL INFLUENCES
   Locale
       The  category  determines whether a right-to-left language has alterna‐
       tive numbers.

   International Code Set Support
       Single-byte character code sets are supported.

WARNINGS
       does not check for overflow of the array pointed to by s1.

   Obsolescent Interfaces
       is to be obsoleted at a future date.
