2.3.4. aocl_mmd_close

The aocl_mmd_close function closes an opened device via its handle.

Syntax

int aocl_mmd_close( int handle );

Function Arguments

handle—A positive int value representing the handle to the board obtained from the aocl_mmd_open() call.

Return Value

If the aocl_mmd_close() executes successfully, the return value is 0.

If aocl_mmd_close() fails to execute, a negative return value indicates an error.
