Segmentation fault

[drordahary]

When initializing slog after I try to log once it fails with segmentation fault.
Here is the code below:

slog_init("logfile", 1, 0);
slog_config_t slg_cfg;
slg_cfg.eColorFormat = SLOG_COLORING_FULL;
slg_cfg.eDateControl = SLOG_TIME_ONLY;
strcpy(slg_cfg.sFileName, "logfile");
strcpy(slg_cfg.sFilePath, "../logs/");

slg_cfg.nTraceTid = 1;
slg_cfg.nToScreen = 0;
slg_cfg.nToFile = 1;
slg_cfg.nUseHeap = 0;
slg_cfg.nFlush = 0;
slg_cfg.nFlags = 1;
slog_config_set(&slg_cfg);

slog_trace("some.");

NOTE: I checked and the directory exists
I found out that what causes it to crash is this: slg_cfg.nFlags = 1;
If I remove that line it runs but doesn't output anything to the file

Hi @drordahary,

This is not an issue. According to your copy, this is an expected result and I will tell you why.

slog_config_t structure has more fields than you are initializing in this example,
so some of the fields are not initialized while you are calling slog_config_set() function.

To fix this problem, you should call slog_config_get() function, which will initialize and fill
all the slog_config_t structure variables from the current configuration and then you can assign
only those parameters which you want to change and set the configuration with slog_config_set().

The correct example should look like:

slog_init("logfile", 1, 0);
slog_config_t slg_cfg;

//////////////////////////////////////////
// get the current configuration
slog_config_get(&slg_cfg);
//////////////////////////////////////////

// Change needed parameters
slg_cfg.eColorFormat = SLOG_COLORING_FULL;
slg_cfg.eDateControl = SLOG_TIME_ONLY;
strcpy(slg_cfg.sFileName, "logfile");
strcpy(slg_cfg.sFilePath, "../logs/");
slg_cfg.nTraceTid = 1;
slg_cfg.nToScreen = 0;
slg_cfg.nToFile = 1;
slg_cfg.nUseHeap = 0;
slg_cfg.nFlush = 0;
slg_cfg.nFlags = SLOG_FLAGS_ALL;

//////////////////////////////////////////
// Activate new configuration
slog_config_set(&slg_cfg);
//////////////////////////////////////////

slog_trace("some.");

Please also note that parameter 1 for nFlags is not a valid value,
You can use SLOG_FLAGS_ALL to enable all the logging flags,
or just elect only needed flags like:

slg_cfg.nFlags = SLOG_INFO | SLOG_ERROR | SLOG_WARN;
