Extension Module Example
Extension modules are used to extend the Python interpreter with functions in C. For example, suppose you had some C code in a file spam.c that you wanted to access from Python as a module named spam. To do this, you first need to know something about the original C code. The following listing shows some sample C functions that we are going to access from Python:
/* file: spam.c */ /* Compute the greatest common divisor of positive integers x and y */ int gcd(int x, int y) { int g; g = y; while (x > 0) { g = x; x = y % x; y = g; } return g; } /* Print some data */ void print_data(char *name, char *email, char *phone) { printf("Name : %s\n", name); printf("Email : %s\n", email); printf("Phone : %s\n", phone); }
