Well, you can check it here - Solaris manual pages say nothing about changing the value of argument...

I still need to get some experience on pointer operations... This code returns some warnings:
If basename(3C) takes pointer and strdup(3C) returns it, why does it "makes pointer from integer"?.. If I got it right, I need to pass to basename function a pointer to the beginning of some memory area, which hold char array, but strdup returns the same thing - "a pointer to a new string that is a duplicate of the string pointed to by s1"... I'm a little bit confused...
And what does mean "impicit declaration..."?
Thanks in advance

thanks all

So after declaration of basename and strdup these warnings disappeared, but why some functions, returning non-integer values, such as readdir(3C) don't need to be declared?..

Hi guys, last cry for help for today. I appreciate the help so far.

Hi all,

Hi, okay, the following command was given to me in a script, but it's not working and there's little to no help on dirname. What is wrong with the following line? I'm just trying to save the current directory to use later in subsequent scripts.
MYAPPDIR=$(dirname $(dirname $0))
Thanks. (2 Replies)
We are using #!/bin/sh
From a command line this command returns the correct list of files (without going into any subdirectories)

I have a list of files generated like this:

basename
DIRNAME(3) Linux Programmer's Manual DIRNAME(3)NAME
dirname, basename - Parse pathname components
SYNOPSIS
#include <libgen.h>
char *dirname(char *path);
char *basename(char *path);
DESCRIPTION
The functions dirname and basename break a null-terminated pathname string into directory and filename components. In the usual case,
dirname returns the string up to, but not including, the final '/', and basename returns the component following the final '/'. Trailing
'/' characters are not counted as part of the pathname.
If path does not contain a slash, dirname returns the string "." while basename returns a copy of path. If path is the string "/", then
both dirname and basename return the string "/". If path is a NULL pointer or points to an empty string, then both dirname and basename
return the string ".".
Concatenating the string returned by dirname, a "/", and the string returned by basename yields a complete pathname.
Both dirname and basename may modify the contents of path, so if you need to preserve the pathname string, copies should be passed to these
functions. Furthermore, dirname and basename may return pointers to statically allocated memory which may be overwritten by subsequent
calls.
The following list of examples (taken from SUSv2) shows the strings returned by dirname and basename for different paths:
path dirname basename
"/usr/lib" "/usr" "lib"
"/usr/" "/" "usr"
"usr" "." "usr"
"/" "/" "/"
"." "." "."
".." "." ".."
EXAMPLE
char *dirc, *basec, *bname, *dname;
char *path = "/etc/passwd";
dirc = strdup(path);
basec = strdup(path);
dname = dirname(dirc);
bname = basename(basec);
printf("dirname=%s, basename=%s
", dname, bname);
free(dirc);
free(basec);
RETURN VALUE
Both dirname and basename return pointers to null-terminated strings.
BUGS
In versions of glibc up to and including 2.2.1, dirname does not correctly handle pathnames with trailing '/' characters, and generates a
segmentation violation if given a NULL argument.
