     mbrtowc — convert a character to a wide-character code (restartable)

     Standard C Library (libc, -lc)

     #include <wchar.h>

     mbrtowc(wchar_t * restrict pwc, const char * restrict s, size_t n,
	 mbstate_t * restrict ps);

     The mbrtowc() function inspects at most n bytes pointed to by s to deter‐
     mine the number of bytes needed to complete the next multibyte character.
     If a character can be completed, and pwc is not NULL, the wide character
     which is represented by s is stored in the wchar_t it points to.

     If s is NULL, mbrtowc() behaves as if pwc was NULL, s was an empty string
     ("") and n was 1.

     The mbstate_t argument, ps, is used to keep track of the shift state.  If
     it is NULL, mbrtowc() uses an internal, static mbstate_t object, which is
     initialized to the initial conversion state at program startup.

     The mbrtowc() functions returns:

     0	     The next n or fewer bytes represent the null wide character

     >0	     The next n or fewer bytes represent a valid character, mbrtowc()
	     returns the number of bytes used to complete the multibyte char‐

	     The next n contribute to, but do not complete, a valid multibyte
	     character sequence, and all n bytes have been processed.

	     An encoding error has occurred.  The next n or fewer bytes do not
	     contribute to a valid multibyte character.

     The mbrtowc() function will fail if:

     [EILSEQ]		An invalid multibyte sequence was detected.

     [EINVAL]		The conversion state is invalid.

     mbtowc(3), multibyte(3), setlocale(3), wcrtomb(3)

     The mbrtowc() function conforms to ISO/IEC 9899:1999 (“ISO C99”).
