I need to read variable name and value combinations from a config file and store the results. I seem to be having no trouble storing the int value, but the strings I am having trouble with. In the first part I am doing some command line processing which looks to be working fine, reading from the config file is tripping me up. Attached are 2 files. project.c is the source and settings.txt is the config
what kind of error do you get?
well...this is what the output gives me
token = group1
groupName = group1
token = 7
timeToRun = 7token = log.txt
logFilename = log.txt
Groupname = TimeToRun = 7 ConfigFilename = settings.conf LogFilename = �����y����l-y������Y.y�p1� ��������
so basically, when I try to store those values that are held in the char* token, they wont save to the global variable Groupname, and LogFilename. I have no idea why. I'm assuming that maybe I need to do a malloc somewhere maybe??? i really don't know C at all and I am just guessing.
Your logfilename is a pointer to a local variable.
When readConfigFile() returns, the string variable you have been using goes out of scope.
You need to allocate space for, and strcpy() the result.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
is that the same problem with the group name too? is that why, at the end when I print out all the variables, the group name is apparently empty?
and how would I do the allocation? malloc(sizeof(char*))???
I figured it out. Thanks so much for the help guys. You have NO idea how long I sat and stared at this. Although I feel like I should have realized what was happening, I'm just not all that familiar with pointers.
