| 9 Name: clipboard | |
| 10 | |
| 11 Synopsis: | |
| 12 int PDC_getclipboard(char **contents, long *length); | |
| 13 int PDC_setclipboard(const char *contents, long length); | |
| 14 int PDC_freeclipboard(char *contents); | |
| 15 int PDC_clearclipboard(void); | |
| 16 | |
| 17 Description: | |
| 18 PDC_getclipboard() gets the textual contents of the system's | |
| 19 clipboard. This function returns the contents of the clipboard | |
| 20 in the contents argument. It is the responsibilitiy of the | |
| 21 caller to free the memory returned, via PDC_freeclipboard(). | |
| 22 The length of the clipboard contents is returned in the length | |
| 23 argument. | |
| 24 | |
| 25 PDC_setclipboard copies the supplied text into the system's | |
| 26 clipboard, emptying the clipboard prior to the copy. | |
| 27 | |
| 28 PDC_clearclipboard() clears the internal clipboard. | |
| 29 | |
| 30 Return Values: | |
| 31 indicator of success/failure of call. | |
| 32 PDC_CLIP_SUCCESS the call was successful | |
| 33 PDC_CLIP_MEMORY_ERROR unable to allocate sufficient memory for | |
| 34 the clipboard contents | |
| 35 PDC_CLIP_EMPTY the clipboard contains no text | |
| 36 PDC_CLIP_ACCESS_ERROR no clipboard support | |
