Hi!
I’m using GLIB to read ini files. I’ve created helper function to use along all parts of my program (written in C).
This is the function to read integer:
int ini_getInteger(char *ini_file, char *section, char *key, int def_value) {
GKeyFile *localini;
GError *error = NULL;
int abc = 0;
localini = g_key_file_new();
if (g_key_file_load_from_file(localini, ini_file, G_KEY_FILE_KEEP_COMMENTS, &error) == FALSE) {
mylog_log("Error loading ini file.\n");
g_key_file_free(localini);
if (error != NULL) {
g_error_free(error);
}
return def_value;
}
abc = g_key_file_get_integer(localini, section, key, &error);
g_key_file_free(localini);
if (error != NULL) {
if (error->code == G_KEY_FILE_ERROR_KEY_NOT_FOUND || error->code == G_KEY_FILE_ERROR_INVALID_VALUE || error->code == G_KEY_FILE_ERROR_GROUP_NOT_FOUND) {
g_error_free(error);
return def_value;
} else {
g_error_free(error);
return abc;
}
} else {
return abc;
}
}
And this is an example of use (from monitor.c):
if (ini_getInteger(config_file, "server", "debug_level", 0) != debug_level) {
debug_level = ini_getInteger(config_file, "server", "debug_level", 0);
}
The function is working, I’m getting the correct value. The problem is that I’m getting memory leak too.
This is the output from valgrind:

What am I doing wrong?
