Tcl_UniCharIsAlpha(3)Tcl Library Procedures Tcl_UniCharIsAlpha(3)

DESCRIPTION

     All of  the  routines  described  examine  Tcl_UniChars  and
     return  a  boolean value. A non-zero return value means that
     the character does belong to the character class  associated
     with  the  called  routine.  The  rest of this document just
     describes the character classes associated with the  various
     routines.

     Note: A Tcl_UniChar is a Unicode character represented as an
     unsigned, fixed-size quantity.

CHARACTER CLASSES

     Tcl_UniCharIsAlnum tests if the character is an alphanumeric
     Unicode character.

     Tcl_UniCharIsAlpha tests if the character is  an  alphabetic
     Unicode character.

     Tcl_UniCharIsControl tests if the  character  is  a  Unicode
     control character.

     Tcl_UniCharIsDigit tests  if  the  character  is  a  numeric
     Unicode character.

     Tcl_UniCharIsGraph tests if the  character  is  any  Unicode
     print character except space.

     Tcl_UniCharIsLower tests if the  character  is  a  lowercase
     Unicode character.

     Tcl_UniCharIsPrint tests if the character is a Unicode print
     character.

     Tcl_UniCharIsPunct tests if the character is a Unicode punc-
     tuation character.

     Tcl_UniCharIsSpace tests if the character  is  a  whitespace
     Unicode character.

     Tcl_UniCharIsUpper tests if the character  is  an  uppercase
     Unicode character.

     Tcl_UniCharIsWordChar tests if the character is alphanumeric
     or a connector punctuation mark.

KEYWORDS
