C fclose()
The fclose() function is used to close the file that associated with stream and then flushes its buffer. After a call to fclose() function, stream is no longer connected with the file, and any automatically allocated buffers are deallocated.
fclose() Syntax
Following is the syntax of the fclose() function :
#include<stdio.h> int fclose(FILE *stream);
fclose() functions returns zero on success, otherwise it returns EOF.
fclose() Example
Following c program opens and then closes the file :
#include<stdio.h> #include<conio.h> void main() { clrscr(); FILE *fp; char fname[20]; printf("Enter the file name with extension (like demo.txt) : "); gets(fname); fp=fopen(demo, "rb"); if(fp==NULL) { printf("Error in opening the file..!!\n"); printf("Press any key to exit..\n"); getch(); exit(1); } if(fclose(fp)) { printf("Error in closing the file..!!\n"); } getch(); }
