_mbccpy, _mbccpy_l

Copy a multibyte character from one string to another string. More secure versions of these functions are available; see _mbccpy_s, _mbccpy_s_l.

void _mbccpy(
   unsigned char *dest,
   const unsigned char *src 
);
void _mbccpy_l(
   unsigned char *dest,
   const unsigned char *src,
   _locale_t locale
);

Parameters

  • dest
    Copy destination.

  • src
    Multibyte character to copy.

  • locale
    Locale to use.

Remarks

The _mbccpy function copies one multibyte character from src to dest.

This function validates its parameters. If _mbccpy is passed a null pointer for dest or src, the invalid parameter handler is invoked, as described in Parameter Validation. If execution is allowed to continue, errno is set to EINVAL.

_mbccpy uses the current locale for any locale-dependent behavior. _mbccpy_l is identical to _mbccpy except that _mbccpy_l uses the locale passed in for any locale-dependent behavior. For more information, see Locale.

Security Note Use a null-terminated string. The null-terminated string must not exceed the size of the destination buffer. For more information, see Avoiding Buffer Overruns. Buffer overrun problems are a frequent method of system attack, resulting in an unwarranted elevation of privilege.
