 |
|
Excuse me,
i've a function to list all file in a dir:
| Code: |
n = scandir(dir, &namelist, 0, alphasort);
b=n;
while(b--){
if(a!=n){
a++;
printf("%s\n", namelist[a]->d_name);
}
}
|
but this funct show all the file in the directory!
I will show only the name of the file, not the "." and ".."!
| Code: |
if ((strcmp(namelist[a]->d_name,".") == 0)
....
|
but this function don't work correctly! How to resolve?
( Excuse me for my english, i'm italian )

huh this forum is for PSP development not for C teaching, your question is an evidence about the fact you don't master C and so I may question your choice about messing up with psardump as well.
that would be the last answer I would give you :
strcmp("..", ".") is strictly equivalent to say : does the ".." sequence equal to the "." sequence, which is obviously always false. What you seem to want to do is : is the first character a "." ? which is not enough indeed.
The real thing to do is :
| Code: | if ((filename[0] != '.') ||
((filename[1] != '\0') && ((filename[1] != '.') || (filename[2] != '\0'))))
... |
with this code, you're only excluding "." and "..", if a file is named "..hello", it wouldn't be excluded. |
