The log mask is a global variable in the gensio library that sets what level of logs are delivered through the vlog function pointer in gensio_os_funcs. Log levels are:


with obvious meanings. There is also:


which is a bitmask of all the log levels.

The default log mask is (1 << GENSIO_LOG_FATAL | 1 << GENSIO_LOG_ERR). Setting other log values can be helpful in debugging problems with gensios.

gensio_log_level_to_str converts a log level to a string representation of that level.

gensio_vlog and gensio_log are the functions used to generate logs. These are primarily for use in the gensio library, though you may use them, too, if you like.
