Expand description
@brief Disable and free an interrupt.
Use an interrupt handle to disable the interrupt and release the resources associated with it. If the current core is not the core that registered this interrupt, this routine will be assigned to the core that allocated this interrupt, blocking and waiting until the resource is successfully released.
@note
When the handler shares its source with other handlers, the interrupt status
bits it’s responsible for should be managed properly before freeing it. see
esp_intr_disable
for more details. Please do not call this function in esp_ipc_call_blocking
.
@param handle The handle, as obtained by esp_intr_alloc or esp_intr_alloc_intrstatus
@return ESP_ERR_INVALID_ARG the handle is NULL ESP_FAIL failed to release this handle ESP_OK otherwise
