XPRBgetprobstat

Purpose

Get the problem status.

Synopsis

int XPRBgetprobstat(XPRBprob prob);

Argument

prob

Reference to a problem.

Return value

Bit-encoded BCL status information:

XPRB_GEN

the matrix has been generated;

XPRB_DIR

directives have been added;

XPRB_MOD

the problem has been modified;

XPRB_SOL

the problem has been solved.

Example

The following retrieves the current problem status and (re)solves the problem if it has been modified.
XPRBprob expl2;
int status;
   ...
expl2 = XPRBnewprob("example2");
status = XPRBgetprobstat(expl2);
if((status&amp;XPRB_MOD)==XPRB_MOD)
  XPRBsolve(expl2, ""); 
Further information

This function returns the current BCL problem status. Note that the problem status uses bit-encoding contrary to the LP and MIP status information, because several states may apply at the same time.
