Hi all,
Can anyone tell me a little about the datatype FILE, which represents stream. What does its structure look like, and in which header file is it defined and so on...
Ex :
FILE *fp ;

Dear colleagues,
One of my friend have a problem with c code. While compiling a c program it displays a message like
"array type has incomplete element type". Any body can provide a solution for it.

closedir
DIRECTORY(3) Library Functions Manual DIRECTORY(3)NAME
opendir, readdir, telldir, seekdir, rewinddir, closedir - directory operations
SYNOPSIS
#include <sys/types.h>
#include <sys/dir.h>
DIR *opendir(filename)
char *filename;
struct direct *readdir(dirp)
DIR *dirp;
long telldir(dirp)
DIR *dirp;
seekdir(dirp, loc)
DIR *dirp;
long loc;
rewinddir(dirp)
DIR *dirp;
closedir(dirp)
DIR *dirp;
DESCRIPTION
Opendir opens the directory named by filename and associates a directory stream with it. Opendir returns a pointer to be used to identify
the directory stream in subsequent operations. The pointer NULL is returned if filename cannot be accessed, or if it cannot malloc(3)
enough memory to hold the whole thing.
Readdir returns a pointer to the next directory entry. It returns NULL upon reaching the end of the directory or detecting an invalid
seekdir operation.
Telldir returns the current location associated with the named directory stream.
Seekdir sets the position of the next readdir operation on the directory stream. The new position reverts to the one associated with the
directory stream when the telldir operation was performed. Values returned by telldir are good only for the lifetime of the DIR pointer
from which they are derived. If the directory is closed and then reopened, the telldir value may be invalidated due to undetected direc-
tory compaction. It is safe to use a previous telldir value immediately after a call to opendir and before any calls to readdir.
Rewinddir resets the position of the named directory stream to the beginning of the directory.
Closedir closes the named directory stream and frees the structure associated with the DIR pointer.
Sample code which searchs a directory for entry ``name'' is:
len = strlen(name);
dirp = opendir(".");
for (dp = readdir(dirp); dp != NULL; dp = readdir(dirp))
if (dp->d_namlen == len && !strcmp(dp->d_name, name)) {
closedir(dirp);
return FOUND;
}
closedir(dirp);
return NOT_FOUND;
