mbsinit - determine conversion object status
int mbsinit(const mbstate_t *ps);
If ps is not a null pointer, the mbsinit() function deter-
mines whether the object pointed to by ps describes an ini-
tial conversion state.
The mbsinit() function returns non-zero if ps is a null
pointer, or if the pointed-to object describes an initial
conversion state; otherwise, it returns 0.
If an mbstate_t object is altered by any of the functions
described as "restartable", and is then used with a dif-
ferent character sequence, or in the other conversion direc-
tion, or with a different LC_CTYPE category setting than on
earlier function calls, the behavior is undefined. See
No errors are defined.
The mbstate_t object is used to describe the current conver-
sion state from a particular character sequence to a wide-
character sequence (or vice versa) under the rules of a par-
ticular setting of the LC_CTYPE category of the current
The initial conversion state corresponds, for a conversion
in either direction, to the beginning of a new character
sequence in the initial shift state. A zero-valued
mbstate_t object is at least one way to describe an initial
conversion state. A zero-valued mbstate_t object can be
used to initiate conversion involving any character
sequence, in any LC_CTYPE category setting.

The mbsinit() function can be used safely in multithreaded
applications, as long as setlocale(3C) is not being called
to change the locale.
