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);
. . .

strncpy(9r)strncpy(9r)NAME
strncpy - General: Copies a null-terminated character string with a specified limit
SYNOPSIS
char * strncpy(
char *s1,
char *s2,
int n );
ARGUMENTS
Specifies a pointer to a buffer of at least n bytes. Specifies a pointer to a string (an array of characters terminated by a null charac-
ter). Specifies the number of characters to be copied.
DESCRIPTION
The strncpy routine copies string s2 to buffer s1. The routine stops copying after it copies a null character or n characters, whichever
comes first. If the length of s2 as determined by the null character is less than n, the routine pads s1 with null characters.
RETURN VALUES
The strncpy routine returns a pointer to /NULL at the end of the first string (or to the location following the last copied character if
there is no NULL). The copied string will not be null terminated if the length of s2 is n characters or more.

Hi ...
I am having a string in the buffer .. It is binary data it may contain space . When i try to append a space in using strcpy it is taking the inbetween \n as the end and appending space ..
How to append space in the binary data in C ?? please let me know
Thanks in advance,
Arun. (2 Replies)
How can I print the memory address of a pointer using printf (or any other STDOUT functions?). I see in Linux its %p but not in unix, help?
