MBTOWC(3)                  Linux Programmer's Manual                 MBTOWC(3)

NAME
       mbtowc - convert a multibyte sequence to a wide character

SYNOPSIS
       #include <stdlib.h>

       int mbtowc(wchar_t *pwc, const char *s, size_t n);

DESCRIPTION
       The  main  case  for this function is when s is not NULL and pwc is not
       NULL.  In this case, the mbtowc() function inspects at most n bytes  of
       the  multibyte  string starting at s, extracts the next complete multi‐
       byte character, converts it to a wide character and stores it at  *pwc.
       It updates an internal shift state known only to the mbtowc() function.
       If  s  does  not  point to a null byte ('\0'), it returns the number of
       bytes that were consumed from s, otherwise it returns 0.

       If the n bytes starting at s do not contain a complete multibyte  char‐
       acter,  or  if they contain an invalid multibyte sequence, mbtowc() re‐
       turns -1.  This can happen even if n >= MB_CUR_MAX,  if  the  multibyte
       string contains redundant shift sequences.

       A  different case is when s is not NULL but pwc is NULL.  In this case,
       the mbtowc() function behaves as above, except that it does  not  store
       the converted wide character in memory.

       A  third  case is when s is NULL.  In this case, pwc and n are ignored.
       The mbtowc() function resets the shift state, only known to this  func‐
       tion,  to  the  initial  state, and returns nonzero if the encoding has
       nontrivial shift state, or zero if the encoding is stateless.

RETURN VALUE
       If s is not NULL, the mbtowc() function returns the number of  consumed
       bytes  starting at s, or 0 if s points to a null byte, or -1 upon fail‐
       ure.

       If s is NULL, the mbtowc() function returns nonzero if the encoding has
       nontrivial shift state, or zero if the encoding is stateless.

NOTES
       The behavior of mbtowc() depends on the LC_CTYPE category of  the  cur‐
       rent locale.

       This  function  is  not multithread safe.  The function mbrtowc(3) pro‐
       vides a better interface to the same functionality.
