memccpy()

Copy bytes between buffers until a given byte is found

Synopsis:

#include <string.h>

void* memccpy( void* dest, 
               const void* src,
               int c,
               size_t cnt );

Arguments:

dest

A pointer to where you want the function to copy the data.

src

A pointer to the buffer that you want to copy data from.

c

The value that you want to stop copying at.

cnt

The maximum number of bytes to copy.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The memccpy() function copies bytes from src to dest, up to and including the first occurrence of the character c, or until cnt bytes have been copied, whichever comes first.

Returns:

A pointer to the byte in dest following the character c, if one is found and copied; otherwise, NULL.

Examples:

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

char* msg = "This is the string: not copied";

int main( void )
{
    char buffer[80];

    memset( buffer, '\0', 80 );
    memccpy( buffer, msg, ':', 80 );

    printf( "%s\n", buffer );
    
    return EXIT_SUCCESS;
}

produces the output:

This is the string:
