Introduction to Library Functions                          CHR(3)

NAME
     chr - character constant conversion routines

SYNOPSIS
          #include <ast.h>

          int          chresc(const char* s, char** e);
          int          chrtoi(const char* s);

DESCRIPTION
     chresc converts and returns the next character  constant  in
     the  0-terminated string s.  If e is not 0 then *e is set to
     point to the next character in s on return.  0  is  returned
     and e is not modified when the end of s is reached.

     chrtoi converts the 0-terminated string  s  to  an  int  and
     returns  the  value.   The  characters in s are converted in
     order from the left and shifted into the int value until  up
     to  the  number  of  characters  in an int is reached.  This
     operation is inherently machine-dependent, but at least  its
     defined in one place.

     The following \ escape sequences are recognized:

     The character represented by the octal code
          ooo.

     The character represented by the hex code
          xx.

     \a   Alert (bell).

     \b   Backspace.

     \f   Formfeed.

     \n   Newline.

     \r   Carriage return.

     \t   Horizontal tab.

     \v   Vertical tab.

     \E   ESC (escape).

     \\   Backslash.

     Other characters following \  are  undefined  (although  for
     backwards compatibility they translate to themselves).
