Access is denied

[TG Naveen]

i have created a file using low level functions.
int Handle
Handle = open ("c:\\windows\\calc_copy.exe" , _O_RDWR | _O_BINARY |
_S_IREAD | _S_IWRITE ) ;

close ( Handle );

after the code compilation. when i tried to delete the file through
dos box.
its give message "Access is denied". how can i set attributes to a
file when creating it or when closing it.

I suggest you use either the "system" command or use platform
specific code. The platform specific code can be found in a
platform specific newsgroup. See the FAQ link below.

There are no such functions as "open()" or "close()" in standard
C. You need to consult a group dealing with your particular
operating system and/or compiler.

Alternatively switch to documented functions such as fopen and
fclose. The results will be portable, and you can ask questions
about it here and/or read the FAQ.

Just a quick note to say this link doesn't work, I tried .co.uk too which I
believe is Demon's domain, but that didn't work either.
