I seriously suggest getting a copy of this book  by Brian W. Kernighan 
<http://www.cs.bell-labs.com/%7Ebwk> and Dennis M. Ritchie 
<http://www.cs.bell-labs.com/%7Edmr>. (here: 
http://cm.bell-labs.com/cm/cs/cbook/).

But in the mean time, you should be able to get away with:

gchar *mystring = "123";
gint myint = 0;

myint = atoi(mystring);

NOTE: this is Ascii TO Integer, if you want Ascii TO Long use atol ...etc.
