chktri - check for trigraphs in C source code
chktri [file ...]
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
188.8.131.52 in the ISO 9899:1990 standard or any decent C book. (You don't
really want to know.)
