Im reading data in from a file and using the values captured to manipulate shape placement in opengl. However, the data I get from the file is for example an 'ascii 0', so when i come to stick this into the function to position it, it doesnt understand that all it is is a 0. Ive seen a toascii() function when looking for an appropriate function, is there a similar function to convert ascii to ints?

Atoi() I think should make the trick
good sir, i could eat you... but i wont. ty
The FAQ. Maybe that will help you.
When all else fails, read the instructions.

ok, im still having problems. Ill describe what im doing.
I have a text file that has a list of numbers and letters, this data im going to process and turn it into data to place opengl objects. the format of the data in the file is like:
a001 b020
I read these into an array using fgets.
I evaluate the contents of the array, if it finds 'a' for example it then uses the next 3 numbers of the array as coordinates. in this case 0, 0, 1. Because im using the data individually the atoi() function i was told about isnt of much help as it takes one number and converts it and ignores the char data. I cant think of a way round this, any ideas?
Code:char line[] = "a001 b020"; int n1, n2, n3; n1 = line[1] - '0'; n2 = line[2] - '0'; n3 = line[3] - '0';
it worked!
