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
number 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 alternative 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.
