NAME

       fcft_log_init - configure logging in fcft

SYNOPSIS

       #include <fcft/fcft.h>

       void fcft_log_init(
           enum fcft_log_colorize colorize, bool do_syslog, enum fcft_log_class log_level);

DESCRIPTION

       By default, fcft does not log anything; use fcft_log_init() to enable, and configure
       logging in fcft.

       fcft_log_init() is typically called early, at program startup.

       colorize is one of:

           enum fcft_log_colorize {
               FCFT_LOG_COLORIZE_NEVER,
               FCFT_LOG_COLORIZE_ALWAYS,
               FCFT_LOG_COLORIZE_AUTO
           };

       FCFT_LOG_COLORIZE_AUTO enables colors if stderr is a TTY.

       if do_syslog is set, fcft will log to syslog, in addition to the regular logging on
       stderr.

       Note that fcft does not call openlog(), even if do_syslog is set. Do this from the calling
       application. Before, or after calling fcft_log_init() does not matter, as long as it is
       done before calling any other fcft API functions.

       Finally, log_level configures which types of log messages that will be shown.

           enum fcft_log_class {
               FCFT_LOG_CLASS_NONE,
               FCFT_LOG_CLASS_ERROR,
               FCFT_LOG_CLASS_WARNING,
               FCFT_LOG_CLASS_INFO,
               FCFT_LOG_CLASS_DEBUG
           };

       Note that this is not a bitmask; setting FCFT_LOG_CLASS_INFO, also enables
       FCFT_LOG_CLASS_WARNING and FCFT_LOG_CLASS_ERROR.
