NAME
btowc - convert single byte to wide character SYNOPSIS
#include
wintt btowc(int c); DESCRIPTION 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. RETURN VALUE The btowc() function returns the wide character converted from the sin‐ gle byte c. If c is EOF or not a valid multibyte sequence of length 1, it returns WEOF.

C99, POSIX.1-2001. NOTES The behavior of btowc() depends on the LCCTYPE 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 either mbtowc(3) or the thread-safe mbr‐ towc(3) instead. SEE ALSO mbrtowc(3), mbtowc(3), wctob(3) COLOPHON
