Constructors, Assignment and Destructor
int	ppl_new_Constraint_System (ppl_Constraint_System_t *pcs)
	Builds an empty system of constraints and writes a handle to it at address `pcs`. More...

int	ppl_new_Constraint_System_zero_dim_empty (ppl_Constraint_System_t *pcs)
	Builds a zero-dimensional, unsatisfiable constraint system and writes a handle to it at address `pcs`. More...

int	ppl_new_Constraint_System_from_Constraint (ppl_Constraint_System_t *pcs, ppl_const_Constraint_t c)
	Builds the singleton constraint system containing only a copy of constraint `c`; writes a handle for the newly created system at address `pcs`. More...

int	ppl_new_Constraint_System_from_Constraint_System (ppl_Constraint_System_t *pcs, ppl_const_Constraint_System_t cs)
	Builds a constraint system that is a copy of `cs`; writes a handle for the newly created system at address `pcs`. More...

int	ppl_assign_Constraint_System_from_Constraint_System (ppl_Constraint_System_t dst, ppl_const_Constraint_System_t src)
	Assigns a copy of the constraint system `src` to `dst`. More...

int	ppl_delete_Constraint_System (ppl_const_Constraint_System_t cs)
	Invalidates the handle `cs:` this makes sure the corresponding resources will eventually be released. More...

Functions that Do Not Modify the Constraint System
int	ppl_Constraint_System_space_dimension (ppl_const_Constraint_System_t cs, ppl_dimension_type *m)
	Writes to `m` the dimension of the vector space enclosing `cs`. More...

int	ppl_Constraint_System_empty (ppl_const_Constraint_System_t cs)
	Returns a positive integer if `cs` contains no (non-trivial) constraint; returns 0 otherwise. More...

int	ppl_Constraint_System_has_strict_inequalities (ppl_const_Constraint_System_t cs)
	Returns a positive integer if `cs` contains any (non-trivial) strict inequality; returns 0 otherwise. More...

int	ppl_Constraint_System_begin (ppl_const_Constraint_System_t cs, ppl_Constraint_System_const_iterator_t cit)
	Assigns to `cit` a const iterator "pointing" to the beginning of the constraint system `cs`. More...

int	ppl_Constraint_System_end (ppl_const_Constraint_System_t cs, ppl_Constraint_System_const_iterator_t cit)
	Assigns to `cit` a const iterator "pointing" past the end of the constraint system `cs`. More...

int	ppl_Constraint_System_OK (ppl_const_Constraint_System_t cs)
	Returns a positive integer if `cs` is well formed, i.e., if it satisfies all its implementation invariants; returns 0 and perhaps makes some noise if `cs` is broken. Useful for debugging purposes. More...

Functions that May Modify the Constraint System
int	ppl_Constraint_System_clear (ppl_Constraint_System_t cs)
	Removes all the constraints from the constraint system `cs` and sets its space dimension to 0. More...

int	ppl_Constraint_System_insert_Constraint (ppl_Constraint_System_t cs, ppl_const_Constraint_t c)
	Inserts a copy of the constraint `c` into `cs`; the space dimension is increased, if necessary. More...
