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.

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.
