Overview
The wcstombs() function converts a wide character string wcstring into a multibyte character string, mbstring, beginning in the initial conversion state. Up to nbytes bytes are stored in mbstring. Partial multibyte characters at the end of the string are not stored. The multibyte character string is null terminated if there is room.
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.
