BCL C library functions

A large number of routines are available within the Xpress Builder Component Library, BCL, ranging from simple routines for the creation and solution of problems to sophisticated callback functions and interaction with the Xpress Optimizer library.

In BCL, references to modeling objects (problem definitions, variables, constraints, sets, and bases) have the following types:

XPRBprob

a problem definition;

XPRBvar

a variable;

XPRBarrvar

a one-dimensional array, with elements of type XPRBvar;

XPRBctr

a constraint;

XPRBcut

a cut;

XPRBsol

a solution;

XPRBsos

a Special Ordered Set (SOS1 of SOS2);

XPRBidxset

an index set;

XPRBbasis

a basis.
