wl_eglstream
error { bad_alloc, bad_handle, bad_attribs, bad_address }
参数 | 值 | 描述 |
|---|---|---|
| bad_alloc | 0 | 分配错误 |
| bad_handle | 1 | 句柄错误 |
| bad_attribs | 2 | 属性错误 |
| bad_address | 3 | IP 地址错误 |
attrib { inet_addr, inet_port, y_inverted }
参数 | 值 | 描述 |
|---|---|---|
| inet_addr | 0 | Inet IPv4 地址 |
| inet_port | 1 | IP 端口 |
| y_inverted | 2 | 图像 Y 反转位 |
create_stream(id: new_id<wl_buffer>, width: int, height: int, handle: fd, type: int, attribs: array)
参数 | 类型 | 描述 |
|---|---|---|
| id | new_id<wl_buffer> | New ID |
| width | int | Stream framebuffer width |
| height | int | Stream framebuffer height |
| handle | fd | Handle for the stream creation |
| type | int | Handle type |
| attribs | array | Stream extra connection attribs List of attributes with extra connection data It contains key-value pairs compatible with intptr_t type. A key must be one of wl_eglstream_display_attrib enumeration values. What a value represents is attribute-specific. |
创建对应于给定句柄的 wl_buffer。属性列表可用于定义额外的 EGLStream 连接数据（如 inet 地址/端口）。 服务器可以使用 wl_buffer 中编码的信息创建其 EGLStream 句柄。
设置给定 EGLStream 消费者的交换间隔。交换间隔在服务器端被静默限制在有效范围内。
caps(caps: int)
参数 | 类型 | 描述 |
|---|---|---|
| caps | int | Capabilities mask |
在绑定 wl_eglstream_display 时发送能力事件。 它允许服务器通告其支持的功能，以便客户端知道哪些是安全可用的。
swapinterval_override(swapinterval: int, stream: object<wl_buffer>)
参数 | 类型 | 描述 |
|---|---|---|
| swapinterval | int | Server swap interval override value |
| stream | object<wl_buffer> | wl_buffer corresponding to an EGLStream |
当客户端通过 swap_interval() 请求交换间隔设置，且存在覆盖使该请求被忽略时，将发出 swapinterval_override 事件。 swapinterval_override 事件将提供覆盖值，以便客户端知晓。
cap { stream_fd, stream_inet, stream_socket }
参数 | 值 | 描述 |
|---|---|---|
| stream_fd | 1 | 使用 FD 的流连接 |
| stream_inet | 2 | 流 inet 连接 |
| stream_socket | 4 | 流 unix 连接 |
此枚举值应作为位掩码使用。
