uucopy

uucopy(2)							   System Calls 							 uucopy(2)

NAME

       uucopy - no-fault memory-to-memory copy

SYNOPSIS

       #include <strings.h>

       int uucopy(const void *s1, void *s2, size_t n);

DESCRIPTION

       The uucopy() function copies n bytes from memory area s1 to s2.	Copying  between objects that overlap could corrupt one or both buffers.

       Unlike  bcopy(3C),  uucopy()  does  not	cause a segmentation fault if either the source or destination buffer includes an illegal address.
       Instead, it returns -1 and sets errno to EFAULT. This error could occur after the operation has partially completed, so the contents of the
       buffer at s2 are defined if the operation fails.

RETURN VALUES

       Upon successful completion, uucopy() returns 0.	Otherwise, the function returns -1 and	set errno to indicate the error.

ERRORS

       The uucopy() function will fail if:

       EFAULT	 Either the s1 or s2 arguments points to an illegal address.
