(6) Closing files (_CLOSEALL)
214
Normally, output to files is held in a buffer area in memory, and only when the buffer becomes
full is the data actually written to the external recording device. Hence if a file is not closed
properly, it is possible that data output to a file may not actually be written to the external
recording device.
In the case of a program intended for embedded use, normally the program is not terminated.
However, if the main function is terminated due to a program error or for some other reason,
any open files must all be closed.
This processing closes all the files that are open at the time of termination of the main function.
An example of a program to close all the open files is shown below.
// File-type data declaration in C language
struct_iobuf{
}iob[_nfiles];
#include <stdio.h>
#ifdef _ _cplusplus
extern "C"
#endif
void _CLOSEALL(void)
{
int i;
}
2. In the case of a console or other dialog-based device, a flag is set to prevent the use of
