Function oc_wasm_safe::computer::pull_signal

pub fn pull_signal(buffer: &mut [u8]) -> Result<Option<&mut [u8]>>

Pops a signal from the signal queue.

The buffer parameter identifies where to store the signal data.

If there is a signal pending, the signal data is written to buffer as a CBOR-encoded sequence containing the name followed by any additional signal parameters, a slice referring to it is returned, and the signal is removed from the queue. If not, None is returned.

Errors

• BufferTooShort is returned if buffer is not large enough to hold the signal data.

On error, the signal remains in the queue.
