3 Using the CLooG Library

The CLooG Library was implemented to allow the user to call CLooG directly from his programs, without file accesses or system calls. The user only needs to link his programs with C libraries. The CLooG library mainly provides one function (cloog_clast_create_from_input) which takes as input the problem description with some options, and returns the data structure corresponding to the generated code (a struct clast_stmt structure) which is more or less an abstract syntax tree. The user can work with this data structure and/or use our pretty printing function to write the final code in either C or FORTRAN. Some other functions are provided for convenience reasons. These functions as well as the data structures are described in this section.
