Oct-escape

Fixtype of octal escape sequences [C:6.4.4.4] [C:A.1.5].

This is a tagged union type, introduced by fty::deftagsum.

Member Tags → Types

:one → oct-escape-one

:two → oct-escape-two

:three → oct-escape-three

This corresponds to octal-escape-sequence in the grammar in [C]. An octal escape sequence consists of a backslash (implicit in this fixtype definition) followed by one, two, or three octal digits.
