    wcswidth - number of column positions of a wide-character string
     
    

    SYNOPSIS

    #include <wchar.h>

    int wcswidth(const wchar_t *pwcs, size_t n);
     

    DESCRIPTION

    The wcswidth() function shall determine the number of column positions required for n wide-character codes (or fewer than n wide-character codes if a null wide-character code is encountered before n wide-character codes are exhausted) in the string pointed to by pwcs.  

    RETURN VALUE

    The wcswidth() function either shall return 0 (if pwcs points to a null wide-character code), or return the number of column positions to be occupied by the wide-character string pointed to by pwcs, or return -1 (if any of the first n wide-character codes in the wide-character string pointed to by pwcs is not a printable wide-character code).  

    ERRORS

    No errors are defined.
