memcpy()

Copy bytes from one buffer to another

#include <string.h>

void* memcpy( void* dst,
              const void* src,
              size_t length );

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.

length

The 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 memcpy() function copies length bytes from the buffer pointed to by src into the buffer pointed to by dst.

Returns:

A pointer to the destination buffer (that is, the value of dst).

Examples:

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

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

    memcpy( buffer, "Hello", 5 );
    buffer[5] = '\0';
    printf( "%s\n", buffer );
    
    return EXIT_SUCCESS;
}
