I need help stat!!!

[TaiL]

I am using stat() to find the size of a file but for some reason I am returned a constant file size. Here's what i have for code

struct stat statdata;
	static struct stat largestFiles[3];
	
	int i = 0;
	int x =0;
	dentry = readdir(dpntr);
	while(dentry != 0){
		
		i=0;

		if(strcmp((dentry->d_name),"..") > 0){
			if(!stat(filepathname, &statdata)){
				
			        printf("FilePathName: 	%s\n", filepathname);
				printf("FileName:	%s\n",dentry->d_name);
				printf("Size of statdata %d\n\n\n ", statdata.st_size);

and here's what the print out is

FilePathName: /home/this/me/prog
FileName: Asg
Size of statdata 512


FilePathName: /home/this/me/prog
FileName: Asg2
Size of statdata 512


FilePathName: /home/this/me/prog
FileName: Asg3
Size of statdata 512

I can't figure out where the 512 is coming from but each file is approx. 10-15kb. Can someone spot the not?

You're scalling stat() with filepathname each time, which is always /home/this/me/prog. Presumably you want to stat dentry->d_name instead (making sure you're in the correct directory, or building a path by combining filepathname and dentry->d_name).

That made a lot of since. Thanks for that insight. I was just wondering though with new fix I still get 512 printed out on some of the files. Is there a reason for this or did I not completely fix the problem.

struct stat statdata;
	char filepath[256];
	char *file;
	static struct stat largestFiles[3];
	
	int i = 0;
	int x =0;
	dentry = readdir(dpntr);
	while(dentry != 0){
		
		i=0;

		if(strcmp((dentry->d_name),"..") > 0){

			file = dentry->d_name;
			printf("File name is: %s\n", file);
			sprintf(filepath, "%s/%s",filepathname,file);
			printf("FullPathName: %s \n", filepath);

			if(!stat(filepath, &statdata)){

				
				int size = statdata.st_size;
				printf("Size of %s is %d\n\n\n ", file, size);

printout is

File name is: sqlnet.log
FullPathName: /home/it02/me/prog/sqlnet.log
Size of sqlnet.log is 4925


File name is: country.sql.txt
FullPathName: /home/it02/me/prog/country.sql.txt
Size of country.sql.txt is 23888


File name is: untitled folder
FullPathName: /home/it02/me/prog/untitled folder
Size of untitled folder is 512

that last file didn't seem to have anything in it but it returned 512 again

Judging by the name, I'd say the last file is actually a folder.

You should check these against the sizes listed in your file browser (for windows, the file browser is Explorer, I think you can get file sizes by using the "details" type listing). Notice a folder does have a size, they are usually all multiples of a block size (which 512 is).

[TaiL]

Yeah i think you guys are right about size of 512 being folders. I however thought that even if a folder is passed in wouldn't stat still be able to find the size of the folder?

The st_size field of struct stat applies to regular files only, not directories, sockets, or r/b device files.
