File Access Constants
| Constant | Value | Description |
|---|---|---|
| kEdsAccess_Error | -1 |
Error |
| kEdsAccess_Read | 0 |
Open a read-only stream. |
| kEdsAccess_ReadWrite | 2 |
Allow reading and writing. |
| kEdsAccess_Write | 1 |
Open a write-only stream. |
File Create Disposition Constants
| Constant | Value | Description |
|---|---|---|
| kEdsFileCreateDisposition_CreateAlways | 1 |
Creates a new file. If the designated file already exists, that file is overwritten and existing attributes is erased. |
| kEdsFileCreateDisposition_CreateNew | 0 |
Creates a new file. An error occurs if the designated file already exists. |
| kEdsFileCreateDisposition_OpenAlways | 3 |
If the file exists, it is opened. If the designated file does not exist, a new file is created. |
| kEdsFileCreateDisposition_OpenExisting | 2 |
Opens a file. An error occurs if the designated file does not exist. |
| kEdsFileCreateDisposition_TruncateExsisting | 4 |
Opens a file and sets the file size to 0 bytes. |
Seek Origin Constants
| Constant | Value | Description |
|---|---|---|
| kEdsSeek_Begin | 1 |
Moves the file position indicator from the beginning of the stream forward by inOffset bytes. |
| kEdsSeek_Cur | 0 |
Moves the file position indicator from the current position in the stream forward by inOffset bytes. |
| kEdsSeek_End | 2 | Moves the file position indicator from the end of the stream by offset bytes. more |
