93 void gw_log_init (const char *app_name);
95 Initialises the log-system. Application name is given by 'app_name' -
96 could be specified as argv[0]. The application name should not
99 All log messages are directed to stderr on return from this function.
100 Override this behaviour by using the gw_log_file function.
102 The log level is set to GW_LOG_DEFAULT. Override this with the
103 gw_log_level function.
105 The session id is set to 0. Use gw_log_session to change this.
108 void gw_log_level (unsigned level);
110 Sets the log to 'level' by using the GW_LOG_xxxx masks as described
114 void gw_log_session (int session);
116 Sets the session id to 'session'.
119 int gw_log_file (unsigned level, const char *fname);
121 Specifies that output given by 'level' should be appended to file 'fname'.
122 Thus, all log messages can be written to one file or several files.
123 If 'level' is GW_LOG_ALL all output is appended to the same file.
124 If 'fname' is NULL it means that the output is written to stderr.
125 If 'fname' is "" it means the output is written to stdout.
127 This function returns 0 on success; -1 on failure.
130 int gw_log (unsigned level, const char *event_type, const char *format, ...);
132 Append log message to one or more files. The value of parameter
133 'level' and the value given by the last gw_log_level call are bitwise
134 AND'ed. This value represents the log level for this message.
135 If this value is non-zero the 'event_type' and 'format' are used to
136 create the log entries which are appended to the log files specified by
137 the gw_log_file call(s).
139 The 'event_type' should not contain blanks.
140 This function returns 0 on success; -1 on failure.
143 char *gw_strdup (const char *s);
145 Works as strdup(3s), which is not defined by ANSI.
150 <appname> <session> <date> <level> <type> <parameter>
152 Assuming that a 'token' is separated by one or more blanks we have:
156 <date> one token yymmddhhmmss
160 <parameter> zero or more tokens.
