23 gru 2009 · fclose() will flush any unwritten output (via fflush()) before returning, so the error results from the underlying write() won't be reported at fwrite() or fprintf() time, but when you do the fclose(). As a result, any error that write() or fflush() can generate can be generated by fclose().
The C library fclose() function is used to close an open file stream. It closes the stream and all buffers are flushed. Syntax. Following is the C library syntax of the fclose() function −. int fclose(FILE *stream); Parameters. This function accepts only a single parameter −
fclose() Declaration: int fclose(FILE *fp); fclose() function closes the file that is being pointed by file pointer fp. In a C program, we close a file as below. fclose (fp); gets() Declaration: char *gets (char *string) gets functions is used to read the string (sequence of characters) from keyboard input.
The fclose () function defined in the stdio.h header file. It helps to close the stream pointed by the specified 'stream'. Before closing, it deletes all buffers that are associated with the stream. int fclose (FILE *stream); #where stream should be a file pointer.
fclose. Defined in header <stdio.h> int fclose( FILE *stream ); Closes the given file stream. Any unwritten buffered data are flushed to the OS. Any unread buffered data are discarded.
