NAME

       ovbcopy - General: Copies a byte string with a specified limit

SYNOPSIS

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

ARGUMENTS

       Specifies  a  pointer  to  a  string  of  bytes.  Specifies a pointer to a buffer of at least n bytes.  Specifies the number of bytes to be
       copied.

DESCRIPTION

       The ovbcopy routine copies n bytes from string b1 to buffer b2.	No check is made for null bytes.

       The address ranges of b1 and b2 can overlap.

NOTES

       In most cases, ovbcopy is not as efficient as bcopy.

RETURN VALUES

       None

NAME

       strcpy, strncpy - copy a string

SYNOPSIS

       #include <string.h>

       char *strcpy(char *dest, const char *src);

       char *strncpy(char *dest, const char *src, size_t n);

DESCRIPTION

       The  strcpy() function copies the string pointed to by src (including the terminating `' character) to the array pointed to by dest.  The
       strings may not overlap, and the destination string dest must be large enough to receive the copy.

       The strncpy() function is similar, except that not more than n bytes of src are copied. Thus, if there is no null byte among  the  first  n
       bytes of src, the result will not be null-terminated.

       In the case where the length of src is less than that of n, the remainder of dest will be padded with nulls.

RETURN VALUE

       The strcpy() and strncpy() functions return a pointer to the destination string dest.

BUGS

       If  the	destination  string  of  a  strcpy() is not large enough (that is, if the programmer was stupid/lazy, and failed to check the size
       before copying) then anything might happen.  Overflowing fixed length strings is a favourite cracker technique.
