有关chmod()

请问:在tc中有关于将文件的属性设置为系统或者隐藏属性，但是有没有将系统或者隐藏属性的文件设置为原来的属性的函数呢？如有，请例举一二.

#include <sys/types.h>
#include <sys/stat.h>
#include <io.h>
#include <stdio.h>
#include <stdlib.h>

void main( void )
{
/* Make file read-only: */
if( chmod( "CHMOD.C", _S_IREAD ) == -1 )
perror( "File not found\n" );
else
printf( "Mode changed to read-only\n" );
system( "echo /* End of file */ >> CHMOD.C" );

/* Change back to read/write: */
if( chmod( "CHMOD.C", _S_IWRITE ) == -1 )
perror( "File not found\n" );
else
printf( "Mode changed to read/write\n" );
system( "echo /* End of file */ >> CHMOD.C" );
}

补充：这是ＶＣ的程序，至于ＴＣ的参数可能要改一改（几年没用ＴＣ，忘了）。
