75// following behavior:
76
77// - halide_acquire_vulkan_context should always store a valid
78// instance/device/queue in the corresponding out parameters,
79// or return an error code.
80// - A call to halide_acquire_vulkan_context is followed by a matching
81// call to halide_release_vulkan_context. halide_acquire_vulkan_context
82// should block while a previous call (if any) has not yet been
83// released via halide_release_vulkan_context.

85// allocator: an internal halide type handle used for allocating resources
86// instance: the vulkan instance handle
87// device: the vulkan device handle
88// physical_device: the vulkan physical device handle
89// queue: the vulkan queue handle
