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 :
[table style="2"]
| Member | Use / Function |
|---|---|
| level | Fill / Empty level of Buffer |
| token | Validity Checking |
| bsize | Buffer size |
| fd | File descriptor using which file can be identified |
| flags | File status flag |
| hold | ungetc character if no buffer space available |
| buffer | Data transfer buffer |
| curp | Current active pointer |
| istemp | Temp. File indicator |
