NAME

6       fcft_log_init - configure logging in fcft
7

SYNOPSIS

9       #include <fcft/fcft.h>
10
11       void fcft_log_init(
12           enum fcft_log_colorize colorize, bool do_syslog, enum
13           fcft_log_class log_level);
14

DESCRIPTION

16       By default, fcft does not log anything; use fcft_log_init() to enable,
17       and configure logging in fcft.
18
19       fcft_log_init() is typically called early, at program startup.
20
21       colorize is one of:
22
23           enum fcft_log_colorize {
24               FCFT_LOG_COLORIZE_NEVER,
25               FCFT_LOG_COLORIZE_ALWAYS,
26               FCFT_LOG_COLORIZE_AUTO
27           };
28
29       FCFT_LOG_COLORIZE_AUTO enables colors if stderr is a TTY.
30
31       if do_syslog is set, fcft will log to syslog, in addition to the regu‐
32       lar logging on stderr.
33
34       Note that fcft does not call openlog(), even if do_syslog is set. Do
35       this from the calling application. Before, or after calling
36       fcft_log_init() does not matter, as long as it is done before calling
37       any other fcft API functions.
38
39       Finally, log_level configures which types of log messages that will be
40       shown.
41
42           enum fcft_log_class {
43               FCFT_LOG_CLASS_NONE,
44               FCFT_LOG_CLASS_ERROR,
45               FCFT_LOG_CLASS_WARNING,
46               FCFT_LOG_CLASS_INFO,
47               FCFT_LOG_CLASS_DEBUG
48           };
49
50       Note that this is not a bitmask; setting FCFT_LOG_CLASS_INFO, also en‐
51       ables FCFT_LOG_CLASS_WARNING and FCFT_LOG_CLASS_ERROR.
