XPRBgetprobstat
XPRBgetprobstat |
Purpose
Synopsis
int XPRBgetprobstat(XPRBprob prob);
Argument
|
prob
|
Reference to a problem.
|
Return value
Bit-encoded BCL status information:
|
XPRB_GEN
|
|
|
XPRB_DIR
|
|
|
XPRB_MOD
|
|
|
XPRB_SOL
|
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&XPRB_MOD)==XPRB_MOD)
XPRBlpoptimize(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.
