该函数返回给定缓冲区的类型。
返回值将是以下常量之一：
| Buffer Type Constant | |
|---|---|
| 常量 | 描述 |
| buffer_fixed | A buffer of fixed size. |
| buffer_grow | A buffer that will "grow" dynamically as data is added |
| buffer_wrap | A buffer where the data will "wrap". When the data being added reaches the limit of the buffer size, the overwrite will be placed back at the start of the buffer, and further writing will continue from that point. |
| buffer_fast | A special "stripped" buffer that is extremely fast to read/write to. Can only be used with buffer_u8 data types, and must be 1 byte aligned. |
buffer_get_type(buffer);
| 参数 | 类型 | 描述 |
|---|---|---|
| buffer | Buffer | The buffer to check. |
type = buffer_get_type(buff);
上面的代码获取变量 buff 中存储的缓冲区类型，并将其存储在变量中。
