using _open and _setmode in visual studio 2015 on windows 10

To use _open
and _setmode
functions in Visual Studio 2015 on Windows 10, you need to include the appropriate header files and link against the required libraries. Here's an example:
c#include <fcntl.h>
#include <io.h>
int main() {
int fileHandle = _open("example.txt", _O_RDONLY | _O_BINARY);
if (fileHandle == -1) {
// handle error
return 1;
}
// Set the file handle to binary mode
_setmode(fileHandle, _O_BINARY);
// Read or write operations on the file handle
// Close the file handle
_close(fileHandle);
return 0;
}
Make sure to include the <fcntl.h>
and <io.h>
header files for the definitions of _open
, _setmode
, and _close
functions.
To link against the required libraries, open your project settings in Visual Studio 2015 and add the following libraries to the linker settings:
legacy_stdio_definitions.lib
legacy_stdio_wide_specifiers.lib
These libraries provide the necessary implementations for the legacy functions used by _open
, _setmode
, and _close
.
Once you have set up the includes and libraries correctly, you should be able to use _open
, _setmode
, and _close
functions in your Visual Studio 2015 project on Windows 10.
