DevEOF

Gets the status of the end of file (EOF) flag for a device. When you use the DevPrev(), DevNext(), or DevSeek() function, the start or end of the device will eventually be reached, and the EOF flag will be set. Use this function to test the EOF flag.

Syntax

DevEOF(hDev)

hDev:

The device handle, returned from the DevOpen() function. The device handle identifies the table where all data on the associated device is stored.

Return Value

1 if the EOF flag has been set, otherwise 0 (zero).

Related Functions

Example

hDev = DevOpen("Log", 0);

WHILE NOT DevEOF(hDev) DO

	Prompt(DevGetField(hDev,"Tag"));

	DevNext(hDev);

END

DevClose(hDev);
