Constructors, Assignment and Destructor | |
| int | ppl_new_Congruence (ppl_Congruence_t *pc, ppl_const_Linear_Expression_t le, ppl_const_Coefficient_t m) |
Creates the new congruence and writes a handle for it at address pc. The space dimension of the new congruence is equal to the space dimension of le. | |
| int | ppl_new_Congruence_zero_dim_false (ppl_Congruence_t *pc) |
Creates the unsatisfiable (zero-dimension space) congruence and writes a handle for it at address pc. | |
| int | ppl_new_Congruence_zero_dim_integrality (ppl_Congruence_t *pc) |
Creates the true (zero-dimension space) congruence , also known as integrality congruence. A handle for the newly created congruence is written at address pc. | |
| int | ppl_new_Congruence_from_Congruence (ppl_Congruence_t *pc, ppl_const_Congruence_t c) |
Builds a congruence that is a copy of c; writes a handle for the newly created congruence at address pc. | |
| int | ppl_assign_Congruence_from_Congruence (ppl_Congruence_t dst, ppl_const_Congruence_t src) |
Assigns a copy of the congruence src to dst. | |
| int | ppl_delete_Congruence (ppl_const_Congruence_t c) |
Invalidates the handle c: this makes sure the corresponding resources will eventually be released. | |
Functions that Do Not Modify the Congruence | |
| int | ppl_Congruence_space_dimension (ppl_const_Congruence_t c, ppl_dimension_type *m) |
Writes to m the space dimension of c. | |
| int | ppl_Congruence_coefficient (ppl_const_Congruence_t c, ppl_dimension_type var, ppl_Coefficient_t n) |
Copies into n the coefficient of variable var in congruence c. | |
| int | ppl_Congruence_inhomogeneous_term (ppl_const_Congruence_t c, ppl_Coefficient_t n) |
Copies into n the inhomogeneous term of congruence c. | |
| int | ppl_Congruence_modulus (ppl_const_Congruence_t c, ppl_Coefficient_t m) |
Copies into m the modulus of congruence c. | |
| int | ppl_Congruence_OK (ppl_const_Congruence_t c) |
Returns a positive integer if c is well formed, i.e., if it satisfies all its implementation invariants; returns 0 and perhaps makes some noise if c is broken. Useful for debugging purposes. | |

| int | ppl_Congruence_ascii_dump (ppl_const_Congruence_t x, FILE *stream) |
Dumps an ascii representation of x on stream. | |
| int | ppl_Congruence_ascii_load (ppl_Congruence_t x, FILE *stream) |
Loads an ascii representation of x from stream. | |
