FILE structure in C Programming
- C Provides smart way to manipulate data using streams
- In stdio.h header file FILE structure is defined
- FILE structure provides us the necessary information about a FILE or stream which performs input and output operations
Structure :
typedef struct
{
short level ;
short token ;
short bsize ;
char fd ;
unsigned flags ;
unsigned char hold ;
unsigned char *buffer ;
unsigned char * curp ;
unsigned istemp;
}FILE ;
Members of Structure :
