btowc, btowc_l, wctob, wctob_l -- convert between wide and single-byte characters


Standard C Library (libc, -lc)


#include <wchar.h> wint_t btowc(int c); int wctob(wint_t c); #include <wchar.h> #include <xlocale.h> wint_t btowc_l(int c, locale_t loc); int wctob_l(wint_t c, locale_t loc);


The btowc() function converts a single-byte character into a correspond- ing wide character. If the character is EOF or not valid in the initial shift state, btowc() returns WEOF. The wctob() function converts a wide character into a corresponding sin- gle-byte character. If the wide character is WEOF or not able to be rep- resented as a single byte in the initial shift state, wctob() returns EOF. The _l-suffixed versions take an explicit locale argument, while the non- suffixed versions use the current global or per-thread locale.

The btowc() and wctob() functions conform to IEEE Std 1003.1-2001 (``POSIX.1'').


The btowc() and wctob() functions first appeared in FreeBSD 5.0. DragonFly 4.9 February 13, 2012 DragonFly 4.9
