NAME

       bcopy - memory operations (LEGACY)

SYNOPSIS

       #include <strings.h>

       void bcopy(const void *s1, void *s2, size_t n);

DESCRIPTION

       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.

RETURN VALUE

       The bcopy() function shall not return a value.

ERRORS

       No errors are defined.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       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)

RATIONALE

       None.

FUTURE DIRECTIONS

       This function may be withdrawn in a future version.
