Releases a foreign block, like
_Block_release, in LispWorks for Macintosh.
A foreign block pointer.
foreign-block-release releases a foreign block. It corresponds to the C function
foreign-block must be the result of foreign-block-copy. In particular, it is an error to call
foreign-block-release on the result of allocate-foreign-block.
In principle, you can also use
foreign-block-release on foreign blocks that you received from foreign code, if the interface says that you need to release them. However, we do not expect this to happen, because proper interface will always free blocks that it allocates or copies
After the call to
foreign-block-release, foreign-block is of type released-foreign-block-pointer.
foreign-block-release has no useful return value.
foreign-block-release is implemented in LispWorks for Macintosh only.
To free a foreign block that was allocated by Lisp, use free-foreign-block.
