NAME

       chktri - check for trigraphs in C source code

SYNOPSIS

       chktri [file ...]

DESCRIPTION

       This  program  looks for lines containing trigraphs in C source code.  Trigraphs are a way
       to represent certain characters in C source  code  as  two  question  marks  and  a  third
       character.   For  example,  a  backslash  could  be  represented  as  `??/'.  For a detail
       specification, see section 5.2.1.1 in the ISO 9899:1990 standard or  any  decent  C  book.
       (You don't really want to know.)
