btowc: převést jeden bajt na široký znak

Originální popis anglicky: btowc - convert single byte to wide character

Návod, kniha: Linux Programmer's Manual

STRUČNĚ

#include <wchar.h>
 
wint_t btowc(int c);

POPIS / INSTRUKCE

The btowc function converts c, interpreted as a multibyte sequence of length 1, starting in the initial shift state, to a wide character and returns it. If c is EOF or not a valid multibyte sequence of length 1, the btowc function returns WEOF.

NÁVRATOVÁ HODNOTA

The btowc function returns the wide character converted from the single byte c. If c is EOF or not a valid multibyte sequence of length 1, it returns WEOF.

NOTES

The behaviour of btowc depends on the LC_CTYPE category of the current locale. This function should never be used. It does not work for encodings which have state, and unnecessarily treats single bytes differently from multibyte sequences. Use the function mbtowc instead.
