Ich kann wie üblich wieder nur mal mit WinAPI dienen.
Die Funktionen die Du wahrscheinlich brauchst sind:
CreateFile() öffnet oder erzeugt eine Datei und gibt ein Handle zurück
ReadFile() selbsterklärend
WriteFile() selbsterklärend
Ich hab hier mal einen kleinen Auszug aus meine API-Doku...
CreateFile...
| Zitat: |
The CreateFile function creates, opens, or truncates a file, pipe, communications resource, disk device, or console. It returns a handle that can be used to access the object. It can also open and return a handle to a directory.
HANDLE CreateFile(
LPCTSTR lpFileName, // address of name of the file
DWORD dwDesiredAccess, // access (read-write) mode
DWORD dwShareMode, // share mode
LPSECURITY_ATTRIBUTES lpSecurityAttributes, // address of security descriptor
DWORD dwCreationDistribution, // how to create
DWORD dwFlagsAndAttributes, // file attributes
HANDLE hTemplateFile // handle of file with attributes to copy
);
|
WriteFile...
| Zitat: |
BOOL WriteFile(
HANDLE hFile, // handle of file to write to
LPCVOID lpBuffer, // address of data to write to file
DWORD nNumberOfBytesToWrite, // number of bytes to write
LPDWORD lpNumberOfBytesWritten, // address of number of bytes written
LPOVERLAPPED lpOverlapped // addr. of structure needed for overlapped I/O
);
|
ReadFile...
| Zitat: |
BOOL ReadFile(
HANDLE hFile, // handle of file to read
LPVOID lpBuffer, // address of buffer that receives data
DWORD nNumberOfBytesToRead, // number of bytes to read
LPDWORD lpNumberOfBytesRead, // address of number of bytes read
LPOVERLAPPED lpOverlapped // address of structure for data
);
