mbsinit(3)
NAME
  mbsinit - Determines whether a multibyte-character string is in the initial
  conversion state

LIBRARY
  Standard C Library (libc.so, libc.a)

SYNOPSIS
  #include <wchar.h>

  int mbsinit(
	  const mbstate_t *ps);

STANDARDS
  Interfaces documented on this reference page conform to industry standards
  as follows:

  mbsinit():  ISO C

  Refer to the standards(5) reference page for more information about
  industry standards and associated tags.

PARAMETERS
  *ps Points to an mbstate object that contains the current conversion state
      of a string.

DESCRIPTION
  The mbsinit() function determines whether the character sequence being
  converted is in the initial conversion state; that is, the function
  determines whether the current character of a character sequence is a
  multibyte character in the initial shift state as defined by the LC_TYPE
  category of the current locale.

  Use this function along with the restartable conversion functions (mbrlen,
  mbrtowc, wcrtomb, mbsrtowcs, wcsrtombs) to convert between multibyte-
  character and wide-character format.	Only restartable conversion functions
  use an mbstate_t parameter.  Therefore, results are undefined when
  restartable and nonrestartable conversion functions operate on the same
  arrays during a conversion operation.

RESTRICTIONS
  The mbsinit() function and restartable versions of conversion routines are
  functional only when used with locales that support shift state encoding.
  Currently, the DIGITAL UNIX product does not provide any locales that use
  shift state encoding and the mbsinit() function returns a nonzero value
  only to indicate that *ps is a null pointer.

RETURN VALUES
  The mbsinit() function returns a nonzero value if *ps is a null pointer or
  ps describes an initial conversion state; otherwise, the function returns
  zero.
