FILE STRUCTURE IN fopen

[puneetmishramau]

hello friends
fopen function in c returns a pointer to a structure type FILE.this is defined in stdio.h as

typedef struct
{
char* _ptr;
int _cnt;
char* _base;
int _flag;
int _file;
int _charbuf;
int _bufsiz;
char* _tmpfname;
}FILE;

can you tell me the meaning of the internal variables of this structure?
hoping a quick reply
