PtFSGetCurrent problem |

| Issue |
When using PtFSGetCurrent function to get a directory path
e.g.x09PtFileSelItem_t *item;
x09 x09item = PtFSGetCurrent(widget);
Later when we look at item->fullpath, we see paths that look like"/home//tom".
Is this double // supposed to be there, because when we use it in an fopen() it fails?

| Solution |
The double slash is the cause of the problem. It is a special series of characters that is designed for node numbers. You can add more then 2 slashes though. This will look like a single slash.
In a simple fopen test, the following program printed out "fopen succeeded".
x09#include <stdio.h>
x09#include <unistd.h>
x09#include <errno.h>
x09void main(int argc, char *argv[], char x09*envp[]){
x09x09FILE *f;
x09x09f = fopen("/home//something/////some.c","r+");
x09if (f != NULL)
x09x09printf("fopen succededn");
x09else
x09x09printf("fopen failed with errno %dn", errno);
x09}
So check for other incorretness in your path. |
