NAME
       gensio_set_log_mask, gensio_get_log_mask, gensio_log_level_to_str, -
       Logging and seting which gensio logs are passed or ignored

SYNOPSIS
       #include <gensio/gensio.h>

       void gensio_set_log_mask(unsigned int mask);

       unsigned int gensio_get_log_mask(void);

       const char *gensio_log_level_to_str(enum gensio_log_levels level);

       void gensio_vlog(struct gensio_os_funcs *o,
                           enum gensio_log_levels level,
                           const char *str, va_list args);

       void gensio_log(struct gensio_os_funcs *o,
                           enum gensio_log_levels level,
                           const char *str, ...);

DESCRIPTION
       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:


              GENSIO_LOG_FATAL GENSIO_LOG_ERR GENSIO_LOG_WARNING
              GENSIO_LOG_INFO GENSIO_LOG_DEBUG

       with obvious meanings.  There is also:


              GENSIO_LOG_MASK_ALL

       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.
