on 64-bit platforms, size_t is probably 64 bits, while int is probably 32 (not always the case though, and is sometimes compiler or compiler-setting specific. Anyway, you should use

Hi ,
could you please clarify me the difference between sun sparc 32-bit and sun sparc 64-bit?
means on which processors these are supporting (pentium processors, sun sparc processors)

I downloaded the iso image from here and burnt it on DVD.
But when I tried installing it..it said boot device not availiable. Do I have to make it bootable?
Is there any other component that I need to write on DVD other than the image?

Can someone try to compile this older version of xtide (attached) on 64-bit Intel/Linux and upload the xttpd binary? I have a friend who needs an older version up and running because the newer version does not support his required harmonic files.

I have a 32bit number and without using for loop,I want to set mbit to n bit.
Say m bit may be 2nd or 5th or 9th or 10th.n bit may be 22nd or 27or 11th bit.
I assume m<n.
Please help me.Thanks

strlcpy
STRLCPY(3) BSD Library Functions Manual STRLCPY(3)NAME
strlcpy, strlcat -- size-bounded string copying and concatenation
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <string.h>
size_t
strlcpy(char * restrict dst, const char * restrict src, size_t dstsize);
size_t
strlcat(char * restrict dst, const char * restrict src, size_t dstsize);
DESCRIPTION
The strlcpy() and strlcat() functions copy and concatenate strings with the same input parameters and output result as snprintf(3). They are
designed to be safer, more consistent, and less error prone replacements for the easily misused functions strncpy(3) and strncat(3).
strlcpy() and strlcat() take the full size of the destination buffer and guarantee NUL-termination if there is room. Note that room for the
NUL should be included in dstsize.
strlcpy() copies up to dstsize - 1 characters from the string src to dst, NUL-terminating the result if dstsize is not 0.
strlcat() appends string src to the end of dst. It will append at most dstsize - strlen(dst) - 1 characters. It will then NUL-terminate,
unless dstsize is 0 or the original dst string was longer than dstsize (in practice this should not happen as it means that either dstsize is
incorrect or that dst is not a proper string).
If the src and dst strings overlap, the behavior is undefined.
RETURN VALUES
Besides quibbles over the return type (size_t versus int) and signal handler safety (snprintf(3) is not entirely safe on some systems), the
following two are equivalent:
n = strlcpy(dst, src, len);
n = snprintf(dst, len, "%s", src);
Like snprintf(3), the strlcpy() and strlcat() functions return the total length of the string they tried to create. For strlcpy() that means
the length of src. For strlcat() that means the initial length of dst plus the length of src.
If the return value is >= dstsize, the output string has been truncated. It is the caller's responsibility to handle this.
EXAMPLES
The following code fragment illustrates the simple case:
char *s, *p, buf[BUFSIZ];
...
(void)strlcpy(buf, s, sizeof(buf));
(void)strlcat(buf, p, sizeof(buf));
To detect truncation, perhaps while building a pathname, something like the following might be used:
char *dir, *file, pname[MAXPATHLEN];
...
if (strlcpy(pname, dir, sizeof(pname)) >= sizeof(pname))
goto toolong;
if (strlcat(pname, file, sizeof(pname)) >= sizeof(pname))
goto toolong;
Since it is known how many characters were copied the first time, things can be sped up a bit by using a copy instead of an append:
char *dir, *file, pname[MAXPATHLEN];
size_t n;
...
n = strlcpy(pname, dir, sizeof(pname));
if (n >= sizeof(pname))
goto toolong;
if (strlcpy(pname + n, file, sizeof(pname) - n) >= sizeof(pname) - n)
goto toolong;
However, one may question the validity of such optimizations, as they defeat the whole purpose of strlcpy() and strlcat(). As a matter of
fact, the first version of this manual page got it wrong.
