Parsing a .conf file with single function call in c -

is there elegant way of parsing .conf file in c program? say, if have normal text file -

param1 = 22 param2 = 99 param34 = 11 param11 = 15 ... 

it'd nice access in 1 function call, smth like:

int c = xfunction(my.conf, param34); 

and c = 11. many in advance.

it better if use linked list follow

struct node {   char *key;   int value; }; 

and assign key value pair node , can add many node during parsing of conf file linked list.

later when search can traverse linked list , check key simple strcmp() , value.
