#include <wchar.h> size_t wcsnrtombs(char *dest, const wchar_t **src, size_t nwc, size_t len, mbstate_t *ps);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
If dest is not NULL, the wcsnrtombs() function converts at most nwc wide characters from the wide-character string *src to a multibyte string starting at dest. At most len bytes are written to dest. The shift state *ps is updated. The conversion is effectively performed by repeatedly calling wcrtomb(dest, *src, ps), as long as this call succeeds, and then incrementing dest by the number of bytes written and *src by one. The conversion can stop for three reasons:
If dest is NULL, len is ignored, and the conversion proceeds as above, except that the converted bytes are not written out to memory, and that no destination length limit exists.
In both of the above cases, if ps is NULL, a static anonymous state known only to the wcsnrtombs() function is used instead.
