Parsing string function

I need a function that does the follows.
It receives as parameters :
1.string
2.delimiter
3.structure
int parse(char *string, char *delimiter, struct struct)
The function shell parse the string which consists data and delimiters, and transfer the data to the struct members.
The function shell check weather the number of parameters (after parsing the message) is equal to the number of members in the structures and return a proper error if neccessary.
e.g.
struct ur{
char param1
char param2
char param3
}
string : "123,USD,abc,"
delimiter : ,
in this case the outcome of the function will be:
param1=123
param2=USD
param3=abc

Need a working function as an answer
Thanks
