Copies while swapping bytes.

#include <stdlib.h>

void swab (const char *src, char *dest, int n);

Parameters

src

Points to the source buffer.

dest

Points to a buffer to which the source buffer is copied, with each pair of bytes swapped.

n

The number of bytes to be copied.

Remarks

Use swab to copy n bytes from the src buffer while swapping each pair of adjacent bytes.

If n is odd, the last byte is copied directly from the src buffer to the dest buffer, with no byte swapping.

Return Values

Nothing.
