_memccpy 

Copies characters from a buffer.


void *_memccpy(
   void *dest,
   const void *src,
   int c,
   size_t count 
);

Parameters

dest

Pointer to the destination.

src

Pointer to the source.

c

Last character to copy.

count

Number of characters.

If the character c is copied, _memccpy returns a pointer to the char in dest that immediately follows the character. If c is not copied, it returns NULL.

The _memccpy function copies 0 or more characters of src to dest, halting when the character c has been copied or when count characters have been copied, whichever comes first.

Security Note   Make sure that the destination buffer is the same size or larger than the source buffer. For more information, see Avoiding Buffer Overruns.
