WCTOMB(3) BSD Library Functions Manual WCTOMB(3)NAME
wctomb, wctomb_l -- convert a wide-character code to a character
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdlib.h>
int
wctomb(char *s, wchar_t wchar);
#include <stdlib.h>
#include <xlocale.h>
int
wctomb_l(char *s, wchar_t wchar, locale_t loc);
DESCRIPTION
The wctomb() function converts a wide character, wchar, into a multibyte character and stores the result in s. The object pointed to by s
must be large enough to accommodate the multibyte character, which may be up to MB_LEN_MAX bytes.
A call with a null s pointer returns nonzero if the current locale requires shift states, zero otherwise; if shift states are required, the
shift state is reset to the initial state.
Although the wctomb() function uses the current locale, the wctomb_l() function may be passed a locale directly. See xlocale(3) for more
information.
RETURN VALUES
If s is NULL, the wctomb() function returns nonzero if shift states are supported, zero otherwise. If s is valid, wctomb() returns the num-
ber of bytes processed in s, or -1 if no multibyte character could be recognized or converted. In this case, wctomb()'s internal conversion
state is undefined.
ERRORS
The wctomb() function will fail if:
[EILSEQ] An invalid multibyte sequence was detected.
[EINVAL] The internal conversion state is invalid.
SEE ALSO mbtowc(3), wcrtomb(3), wcstombs(3), wctob(3), xlocale(3)STANDARDS
The wctomb() function conforms to ISO/IEC 9899:1999 (``ISO C99'').

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it

Greetings,
I'm trying to delete a file with a weird name from within Terminal on a Mac.
It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘.
Here are some examples of what I've tried:

Hi all...
Well guys and gals, I jumped in at the deep end and found things that PERL cannot do by default.
Many tricky terminal escape codes are not catered for so I had to create workarounds.
One thing I searched for was this:

Well, guys I saw a question about GOTO for Python.
So this gave me the inspiration to attempt a GOTO function for 'dash', (bash and ksh too).

This is purely a fun project to see if it is possible in PURE... (3 Replies)
