Hi, I have a very small program where I call execlp() to execute sort.
Everything works fine. But sort has a -T option which can be used to specify a temporary directory. Now when I use -T with execlp() it does not work.

I have read that exec "replaces the current process with a new one".
So I did
$ exec ls
and after this executed, my shell disappeared. I am assuming that my shell had PID xyz, and when I did exec ls, this ls got pid xyz, and when it terminated, there was no more shell process running, and... (5 Replies)

Hello everyone, this is my first post.
I have a task to use a fork to create multiple processes and then use execlp to run another program to add 2 numbers.
The problem I am having is we are supposed to use the exit() call in the execlp to return the small integer. This is a bad way to... (3 Replies)

strlcat
strcpy(9F) Kernel Functions for Drivers strcpy(9F)NAME
strcpy, strlcat, strlcpy, strncat, strncpy, strspn - String operations.
SYNOPSIS
#include <sys/ddi.h>
char *strcpy(char *dst, const char *src);
size_t strlcat(char *dst, const char *src, size_t dstsize);
size_t strlcpy(char *dst, const char *src, size_t dstsize);
char *strncat(char *restrict s1, const char *restrict s2, size_t n);
char *strncpy(char *dst, const char *src, size_t n);
size_t strspn(const char *s1, const char *s2);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
dst, src Pointers to character strings.
s1, s2 Pointers to character strings.
n Count of characters to be copied.
DESCRIPTION
The arguments dst, src, s1 and s2 point to strings. The strcpy(), strlcpy(), strncpy(), strlcat() and strncat() functions all alter their
first argument. These functions do not check for overflow of the array pointed to by the first argument.
strcpy()
The strcpy() function copies characters in the string src to dst, terminating at the first null character in src, and returns dst to the
caller. No bounds checking is done.
strncpy()
The strncpy() function copies src to dst, null-padding or truncating at n bytes, and returns dst. No bounds checking is done.
strlcpy()
The strlcpy() function copies a maximum of dstsize-1 characters (where dstsize represents the size of the string buffer dst) from src to
dst, truncating src if necessary. The result is always null-terminated. The function returns strlen(src). Buffer overflow can be checked
as follows:
if (strlcpy(dst, src, dstsize) >= dstsize)
return (-1);
strncat()
The strncat() function appends a maximum of n characters. The initial character of s2 overrides the null character at the end of s1.
strlcat()
The strlcat() function appends a maximum of (dstsize- strlen(dst)-1) characters of src to dst (where dstsize represents the size of the
string buffer dst). If the string pointed to by dst contains a null-terminated string that fits into dstsize bytes when strlcat() is
called, the string pointed to by dst is a null-terminated string that fits in dstsize bytes (including the terminating null character) when
it completes, and the initial character of src overrides the null character at the end of dst. If the string pointed to by dst is longer
than dstsize bytes when strlcat() is called, the string pointed to by dst is not changed. The function returns min{dst-
size,strlen(dst)}+strlen(src). Buffer overflow can be checked as follows:
if (strlcat(dst, src, dstsize) >= dstsize)
return -1;
strspn()
The strspn() function returns the length of the initial segment of string s1 that consists entirely of characters from string s2.
RETURN VALUES
strcpy(), strncat() and strncpy() return dst.
For strlcat(), strlcpy() and strspn(), see the Description section.
CONTEXT
These functions can be called from user or interrupt context.
