Detailed Description

Platform functions to support shared memory framebuffers for eHVD elements.

Function Documentation

◆ shmfb_create_object()

void* shmfb_create_object	(	const char *	name,
		size_t	size,
		rh_hashmap_t *	handlemap,
		HqnResult *	perr
	)

Create a shared memory object with the size specified.

Parameters

[in]	name	The name of the shared memory object
[in]	size	The size of the shared memory object
[in,out]	handlemap	A hashmap to store the data pointer to shared memory handle correspondence in.
[out]	perr	A location in which an error code is stored, if the shared memory object could not be created.

Returns: A pointer to the shared memory object, or NULL if it could not be created.

◆ shmfb_open_object()

void* shmfb_open_object	(	const char *	name,
		rh_hashmap_t *	handlemap
	)

Try to open an existing shared memory object with the size specified.

Parameters

[in]	name	The name of the shared memory object
[in,out]	handlemap	A hashmap to store the data pointer to shared memory handle correspondence in.

Returns: A pointer to the shared memory object, or NULL if it did not exist.

Variable Documentation

◆ handlemap_invalid

intptr_t handlemap_invalid = ((intptr_t)NULL)

Invalid value for handle map. CreateFileMapping() returns NULL on failure.
