FCreate2 Function

Create a file or open and truncate an existing file, specifying two strongly typed arguments.

Namespace:  XSharp.Core
Assembly:  XSharp.Core (in XSharp.Core.dll) Version: 2.5
	cFileName AS STRING,
	dwAttributes AS DWORD
) AS IntPtr


Type: String
The name of the file to create, including an optional drive, directory, and extension.  SetDefault() and SetPath() settings are ignored; the Windows default is used unless you specify a drive and directory as part of the file name.  No extension is assumed.
If the file already exists, its length is truncated to 0 without warning.
This function sets NetErr() in case of a concurrency control conflict.
Type: UInt32
One of the following constants indicating the attribute to be set when creating the file:
Constant Description
FC_ARCHIVED Archived file
FC_HIDDEN Hidden file
FC_NORMAL Normal read/write file
FC_READONLY Read-only file
FC_SYSTEM System file

Return Value

Type: IntPtr
The DOS file handle number of the new file.
If an error occurs, FCreate2() returns  F_ERROR.  FError() can be used to determine the specific error.
Tip Tip
The low level File IO functions in the X# runtime are using .Net filestreams in the background.
That means that the file handles returned by FOpen() and FCreate() are not 'normal' file handles, but unique identifiers that are used to find the underlying stream object in a collection of streams in the runtime.
That also means that you can't use file handles for functions such as FRead() and FWrite() that were not created in the X# runtime.
If you want to access the underlying FileStream, then you should call the function FGetStream()
This example creates a file called TESTFILE.TXT and opens it for reading and writing:
1ptrHandle := FCreate2("testfile.txt", FC_NORMAL)
2IF ptrHandle = F_ERROR
3    ? DOSErrString(FError())
5    FWrite(ptrHandle, "Hello there")
6    FClose(ptrHandle)
