NAME

SYNOPSIS

DESCRIPTION

Inviz copies from file (or from stdin, if there is no file given) and writes to stdout. These escape sequences are of the form \c
or \nnn
It also specially treats lines that begin \#datatype ...
which are lines containing text to convert to binary numbers (chars, shorts, ints, longs, doubles, or floats).

Backslash sequences \c and \nnn are used to produce the usual C escapes, with the addition of \@ translating to null.

The complete set of `backslash' escape sequences is:

`\\' → `\'
`\@' → null
`\%' → percent
`\b' → backspace
`\f' → formfeed
`\n' → newline
`\r' → return
`\t' → tab
`\nnn' → ascii character with this octal value
`\Innn...' → ascii character with this hex value

Lines that begin \#datatype
are to be translated into binary numbers. Here the datatype is one of {C,S,I,L,F,D}, and means, respectively, that the text on the rest of the line is to be translated into chars, shorts, ints, longs, floats, or doubles. The rest of the line is made up of the usual sort of text representations of numbers, separated by whitespace. When the datavalue is an integer value (whether char, short, int, or long) may be expressed in octal (0nnn), hex (0xnnn or 0Xnnn), or decimal. If the value is octal or hex, the corresponding output value will be unsigned. If decimal, the type is unsigned unless the number begins with `+' or `-', in which case a signed number is output. In all cases, sscanf(3) is initially used to convert the text to a long int or double value, so any restrictions that apply to sscanf(3) conversions also apply here.

EXAMPLES

\#I 0x234 2345
\#F 6.4

2. To output a form feed followed by the integers 5 and 124, the short -16, and finally a string "456abc%" on a new line, use input like:

\f
\#I 5 124
\#S -16
\n456abc%
