bcopy

Copies byte strings.

Format

#include  <strings.h>

void bcopy  (const void *source, void
            *destination, size_t length);

Arguments

source: Pointer to the source string.
destination: Pointer to the destination string.
length: The length (in bytes) of the string.

Description

The bcopy function operates on variable-length strings of bytes. It copies the value of the length argument in bytes from the string in the source argument to the string in the destination argument.

Unlike the string functions, there is no checking for null bytes. If the length argument is 0 (zero), no bytes are copied.

Note that bcopy is equivalent to memcpy, which is defined by the ANSI C Standard. Therefore, using memcpy is recommended for portable programs.
