  NAME

    setchrclass - Initializes character classification table

  LIBRARY

    Standard C Library (libc.a)

  SYNOPSIS

    #include <ctype.h>

    int setchrclass(
      char *chrclass );

  PARAMETERS

    chrclass   A pointer to the name of the datafile containing information
               for the desired character set.  If chrclass is (char*)0, the
               value of the environment variable CHRCLASS is used.

  DESCRIPTION

    The setchrclass() function initializes the table, used by the functions
    and macros(listed in RELATED INFORMATION), to a specific character
    classification set.  The setchrclass() function uses its argument value or
    the value of the environment variable CHRCLASS as the name of the datafile
    containing the information for the desired character set.  These datafiles
    are searched for in the directory /lib/chrclass.

    If chrclass is (char *)0, the value of the environment variable CHRCLASS
    is used.  If CHRCLASS is not set or is undefined, the table retains its
    current initialization value of ascii.

  FILES

    /lib/chrclass   Directory containing the datafiles for setchrclass().

  RETURN VALUES

    If the setchrclass() function does not fill the table, the table will not
    change (initially ascii) and -1 is returned.  If any other errors occur, a
    nonzero value is returned.  If everything works, setchrclass() returns 0.
