The wcsrtombs() function converts wide character to multibyte string. This function converts the wide character string represented by *src to corresponding multibyte character string and is stored in the character array pointed to by dest if dest is not null. A maximum of len characters are written to dest.
size_t wcsrtombs( char* dest, const wchar_t** src, size_t len, mbstate_t* ps )
Parameters: The function accepts four mandatory parameters which are described below:
- dest : Pointer to an array of char elements long enough to store a string of max bytes
- src : Pointer to a wide string to be translated
- len : Maximum number of bytes available in dest array
- ps : Pointer to the conversion state object
Return value : The function returns two value as below:
- On success it returns the number of bytes written to dest(not including the eventual terminating null character)
- If some error occurs then -1 is returned and errno is set to EILSEQ.
Below programs illustrate the above function:
