bcopy

bcopy(9r)																 bcopy(9r)

NAME

       bcopy - General: Copies a series of bytes with a specified limit

SYNOPSIS

       void bcopy(
	       char *b1,
	       char *b2,
	       int n );

ARGUMENTS

       Specifies  a  pointer  to  a  byte string (array of characters).  This pointer can reside in kernel address space or in user address space.
       Specifies a pointer to a buffer of at least n bytes. This pointer can reside in kernel address space or in user address	space.	 Specifies
       the number of bytes to be copied.

DESCRIPTION

       The  bcopy  routine  copies n bytes from string b1 to buffer b2.  No check is made for null bytes. The copy is nondestructive, that is, the
       address ranges of b1 and b2 can overlap.

RETURN VALUES

       None

EXAMPLES

       The following code fragment shows a call to bcopy:

       .  .  .

       struct tc_slot  tc_slot[TC_IOSLOTS];

       .  .  .

       char *cp;

       .  .  .

       bcopy(tc_slot[index].modulename, cp, TC_ROMNAMLEN + 1);

       .  .  .
