Hello,
I'm working on unix with grep (GNU grep) 2.5.1. I'm going through some of the newer regex syntax using Regular Expression Reference - Advanced Syntax a guide.
ls -aLl /bin | grep "\(x\)"
Which works, just highlights 'x' where ever, when ever.

mbtowc
mbtowc(3int)mbtowc(3int)Name
mbtowc - converts a single multibyte character into a character of type wchar_t
Syntax
#include <stdlib.h>
int mbtowc (pwc, s, n)
wchar_t *pwc;
const char *s;
size_t n;
Arguments
pwc The pwc argument is a pointer to the resulting object of type wchar_t.
s The s argument is a pointer to a multibyte character.
n The n argument is the maximum number of bytes of object s that are examined.
Description
If s is not a null pointer, the function determines the number of bytes that comprise the multibyte character pointed to by s. It then
determines the character code for the value (of type wchar_t) that corresponds to that multibyte character (the value of the code corre-
sponding to the null character is zero). If the multibyte character is valid and pwc is not a null pointer, the function stores the code in
the object pointed to by pwc. At most n bytes of the array pointed to by s are examined. This function is affected by the LC_CTYPE cate-
gory of the current locale.
Return Values
If s is a null pointer, the function returns a zero value. If s is not a null pointer, the function returns:
o 0, if s points to the null character
o The number of bytes that comprise the converted multibye character, if the next n or fewer bytes form a valid multibye character
o - -1, if the next n or fewer bytes do not form a valid multibye character
In no case is the value returned greater than n or the value of the MB_CUR_MAX macro.
