Prototype

int _mbsbtype(const unsigned char *str, size_t nbyte);

Description

The nbyte argument specifies the number of bytes from the start of the zero-based string.

The _mbsbtype function inspects the argument str to determine whether the byte at the position specified by nbyte is a single-byte character, or whether it is the leadbyte or trailing byte in a multibyte character. The _mbsbtype function can determine whether the byte pointed at is an invalid character or a NULL byte.

Any invalid bytes in str before nbyte are ignored.

Return Value

The value that _mbsbtype returns is one of the following manifest constants, defined in mbctype.h.
