[Dev-C++] ANSI C: How to split path and filename

[<vil...@ya...>]

Hello,
how do I split my path and my filename?
Example:

c:\things\alfa\myfile.txt

like:   char *thepath ----> c:\things\alfa
        char *thefile ----> myfile.txt

in ANSI C (or C), meaning the same way with DOS or UNIX

There is anywhere to find this kind of things? (I couldn't find in the help
neither in Bob Stout's snippets)

Thanks.

What you can do is a loop, where the condition is " do I find another \ " ?
And you could do like this.
You find the first "\"
copy "c:\" in a string.
Look for another "\"
paste the sequel to the first string
I mean : "things\" to " c:\"
and you get a string with : "c:\things\"
then you look for another "\"
And you have : "alfa\" paste it to your string, and you get
"c:\things\alfa\"
Since you don't have anymore "\" the rest of the string will be a filename.
Use the strstr() function
strcp() ( if I remember the name ).
They are all in the string.h
Hope it helps.

Fabien.

Why wouldn't you go from the end to the beginning, and try to find a '\'?
When you do, everything after is a file, and before is the path. Similar,
but I'd say a little bit faster.

Sure it would be faster. LOL! = P

And for the matter of the "/" (UNIX) and "\" ( DOS ) well,
you could perform a first research on the "/" or the "\".
If you don't get one then you know which one to use, and you could set a
state variable
to remember which one to find next.

Use something like:

#include <string.h>
/* ... */
char s[]=3D"...";

while(strstr(s, "\\")!=3DNULL)
       *strstr(s, "\\")=3D'/';
/* ... */

RE: [Dev-C++] ANSI C: How to split path and filename

[Ioannis V. <no...@ya...>]

The previous code that I sent is for converting a dos/windows path to
unix path. I hadn't read carefully what you have written.  If you want
to split the directory path from the filename in a dos/windows
environment use this:

#include <string.h>
...
char s[]=3D"path\\filename";
char filename[255];
char path[1024];
size_t i;
char *p=3Dstrrchr(s, "\\");

strcpy(filename, p);

for(i=3D0; i<p-s; i++)
  path[i]=3Ds[i];

path[i]=3D'\0';

This can be done better but it is a quick (and error-prone) example.

I   hope   that   you'll   find  the  attached  files  of  some  help.

I suggest that upon splitting the name of the file, the separator is not=20
discarded, instead it is kept as the last char of the path: doing so allows=
=20
you to rebuild the name of the file by joining what has  been  returned  by=
=20
"thepath" (as long as it is not NULL) and what has been returned by=20
"thefile" regardless of which is the separator (i.e. a backslash, a colon=20
or a slash).
