_memccpy

Visual Studio .NET 2003

Copies characters from a buffer.

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

Parameters

dest: Pointer to destination.
src: Pointer to source.
c: Last character to copy.
count: Number of characters.

Return Value

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.

Remarks

The _memccpy function copies 0 or more chars of src to dest, halting when the character c has been copied or when count chars 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.

Requirements

Routine	Required header	Compatibility
_memccpy	<memory.h> or <string.h>	Win 98, Win Me, Win NT, Win 2000, Win XP

For additional compatibility information, see Compatibility in the Introduction.

Libraries

All versions of the C run-time libraries.

Example

// crt_memccpy.c

#include <memory.h>
#include <stdio.h>
#include <string.h>

char string1[60] = "The quick brown dog jumps over the lazy fox";

int main( void )
{
   char buffer[61];
   char *pdest;

   printf( "Function: _memccpy 60 characters or to character 's'\n" );
   printf( "Source: %s\n", string1 );
   pdest = _memccpy( buffer, string1, 's', 60 );
   *pdest = '\0';
   printf( "Result: %s\n", buffer );
   printf( "Length: %d characters\n", strlen( buffer ) );
}

Output

Function: _memccpy 60 characters or to character 's'
Source: The quick brown dog jumps over the lazy fox
Result: The quick brown dog jumps
Length: 25 characters
