mbsrtowcs \- convert a multibyte string to a wide-character string |
.sh synopsis |
.nf |
.b #include <wchar.h> |
.pp |
.bi "size_t mbsrtowcs(wchar_t *restrict " dest ", const char **restrict " src , |

.sh description |
if |
.i dest |
is not null, the |
.br mbsrtowcs () |
function converts the |
multibyte string |
.i *src |
to a wide-character string starting at |
.ir dest . |
at most |
.i len |
wide characters are written to |
.ir dest . |
the shift state |
.i *ps |
is updated. |
the conversion is effectively performed by repeatedly |
calling |
.i "mbrtowc(dest, *src, n, ps)" |
where |
.i n |
is some |
positive number, as long as this call succeeds, and then incrementing |
