Controlling the libsigrok message logging functionality.
int sr_log_callback_set | ( | sr_log_callback | cb, |
void * | cb_data | ||
) |
Set the libsigrok log callback to the specified function.
cb | Function pointer to the log callback function to use. Must not be NULL. |
cb_data | Pointer to private data to be passed on. This can be used by the caller to pass arbitrary data to the log functions. This pointer is only stored or passed on by libsigrok, and is never used or interpreted in any way. The pointer is allowed to be NULL if the caller doesn't need/want to pass any data. |

int sr_log_callback_set_default | ( | void | ) |
int sr_log_loglevel_get | ( | void | ) |
int sr_log_loglevel_set | ( | int | loglevel | ) |
Set the libsigrok loglevel.
This influences the amount of log messages (debug messages, error messages, and so on) libsigrok will output. Using SR_LOG_NONE disables all messages.
Note that this function itself will also output log messages. After the loglevel has changed, it will output a debug message with SR_LOG_DBG for example. Whether this message is shown depends on the (new) loglevel.
loglevel | The loglevel to set (SR_LOG_NONE, SR_LOG_ERR, SR_LOG_WARN, SR_LOG_INFO, SR_LOG_DBG, or SR_LOG_SPEW). |
