WCSTOMBS(3) BSD Library Functions Manual WCSTOMBS(3) NAME
wcstombs, wcstombs_l -- convert a wide-character string to a character string LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <stdlib.h> size_t wcstombs(char *restrict s, const wchar_t *restrict pwcs, size_t n); #include <stdlib.h> #include <xlocale.h> size_t wcstombs_l(char *restrict s, const wchar_t *restrict pwcs, size_t n, locale_t loc); DESCRIPTION
The wcstombs() function converts a wide character string pwcs into a multibyte character string, s, beginning in the initial conversion state. Up to n bytes are stored in s. Partial multibyte characters at the end of the string are not stored. The multibyte character string is null terminated, if there is room. Although the wcstombs() function uses the current locale, the wcstombs_l() function may be passed a locale directly. See xlocale(3) for more information. RETURN VALUES
The wcstombs() function returns the number of bytes converted (not including any terminating null), if successful; otherwise, it returns (size_t)-1. ERRORS
The wcstombs() function will fail if: [EILSEQ] An invalid wide character was encountered. [EINVAL] The conversion state is invalid. SEE ALSO
mbstowcs(3), multibyte(3), wcsrtombs(3), wctomb(3), xlocale(3) STANDARDS
The wcstombs() function conforms to ISO/IEC 9899:1999 (``ISO C99''). BSD
