I didn't find any text in wcsncpy(3) similar to this.  Maybe you read it
elsewhere?  It would be interesting to find the source, if it needs to
be fixed.

yeah, looks like i might have been copying from the wrong man page:

~/man-pages$ grep -r 'of the wide-character string'
./man/man3/wcsdup.3:contents is a duplicate of the wide-character
string pointed to by
./man/man3/wcsncat.3:to the end of the wide-character string pointed
./man/man3/mbsrtowcs.3:up the converted part of the wide-character
string, not including the
./man/man3/mbstowcs.3:up the converted part of the wide-character
string, not including the
./man/man3/wcpcpy.3:returns a pointer to the end of the wide-character string
./man/man3/wcscat.3:to the end of the wide-character string pointed to by
./man/man3/wcsstr.3:It searches for the first occurrence of the
wide-character string
./man/man3/wcstok.3:If the end of the wide-character string is now
./man/man3/wcslen.3:It determines the length of the wide-character
string pointed to
./man/man3/mbsnrtowcs.3:that make up the converted part of the
wide-character string,

you are in a maze of twisty function names, all alike.

Ahhh, I suspect you got it from wcpcpy(3).  That makes sense.

As I told a friend recently, the 'n' in strncpy(3), stpncpy(3),
strncat(3), strndup(3), and of course their wide-string counterparts,
should be interpreted as "strings NO".  :)


Have a lovely day!
Alex
