void bcopy(const void *
s1, void
*s2, size_t n);
The
bcopy() function shall copy
n bytes from the area pointed to
by
s1 to the area pointed to by
s2.
The bytes are copied correctly even if the area pointed to by
s1 overlaps
the area pointed to by
s2.
The
bcopy() function shall not return a value.
No errors are defined.
The following sections are informative.
None.
The
memmove() function is preferred over this function.
The following are approximately equivalent (note the order of the arguments):
bcopy(s1,s2,n) ~= memmove(s2,s1,n)
For maximum portability, it is recommended to replace the function call to
bcopy() as follows:
#define bcopy(b1,b2,len) (memmove((b2), (b1), (len)), (void) 0)
None.
This function may be withdrawn in a future version.
