Format
#include <recio.h>
int _Rclose(_RFILE *fp);
Language Level: ILE C Extension
Threadsafe: Yes.
Description
The _Rclose() function closes the file specified by fp. Before this file is closed, all buffers associated with it are flushed and all buffers reserved for it are released. The file is closed even if an exception occurs. The _Rclose() function applies to all types of files.
Return Value
The _Rclose() function returns zero if the file is closed successfully, or EOF if the close operation failed or the file was already closed. The file is closed even if an exception occurs, and zero is returned.
The value of errno may be set to:
Value | Meaning |
ENOTOPEN | The file is not open. |
EIOERROR | A non-recoverable I/O error occurred. |
EIORECERR | A recoverable I/O error occurred. |
See Table 12 and Table 14 for errno settings.
Example that uses _Rclose()
#include <stdio.h>
#include <stdlib.h>
#include <recio.h>
int main(void)
{
_RFILE *fp;
/* Open the file for processing in arrival sequence. */
if (( fp = _Ropen ( "MYLIB/T1677RD1", "rr+, arrseq=Y" )) == NULL )
{
printf ( "Open failed\n" );
exit ( 1 );
}
else
/* Do some processing */;
_Rclose ( fp );
}
