File Manipulation Win32 API Functions that create, read, and write to files: CreateFile ReadFile WriteFile SetFilePointer CreateFile (1 of 5) CreateFile either creates a new file or opens an existing file. If successful, it returns a handle to the open file; otherwise, it returns a special constant named INVALID_HANDLE_VALUE. Prototype: CreateFile PROTO, pFilename:PTR BYTE, ; ptr to filename desiredAccess:DWORD, ; access mode shareMode:DWORD, ; share mode lpSecurity:DWORD, ; ptr to security attribs creationDisposition:DWORD, ; file creation options flagsAndAttributes:DWORD, ; file attributes htemplate:DWORD ; handle to template file If the file was created successfully, EAX contains a valid file handle. CreateFile (2 of 5) Parameter Description lpFileName Points to a null-terminated string containing either a partial or fully qualified filename (drive:\path\filename). dwDesiredAccess Specifies how the file will be accessed (reading or writing). dwShareMode Controls the ability for multiple programs to access the file while it is open. lpSecurityAttributes Points to a security structure controlling security rights. .
