Return Value
_mbsnbcat returns a pointer to the destination string. No return value is reserved to indicate an error.
Parameters
dest
Null-terminated multibyte-character destination string
src
Null-terminated multibyte-character source string
count
Number of bytes from src to append to dest
Remarks
The _mbsnbcat function appends, at most, the first count bytes of src to dest. If the byte immediately preceding the null character in dest is a lead byte, the initial byte of src overwrites this lead byte. Otherwise the initial byte of src overwrites the terminating null character of dest. If a null byte appears in src before count bytes are appended, _mbsnbcat appends all bytes from src, up to the null character. If count is greater than the length of src, the length of src is used in place of count. The resulting string is terminated with a null character. If copying takes place between strings that overlap, the behavior is undefined.
