# getprobstat

Purpose
Get the problem status of a model.
Synopsis
`int getprobstat(XPRMcontext ctx);`
Argument

ctx | Mosel's execution context

Return value
Bit encoded problem status or 0.
Further information
This function returns the status of the current problem of the given model, or 0 if no problem is available. The problem status is bit encoded as follows:

XPRM_PBCHG | Problem loaded in the optimizer (if any) is not valid
XPRM_PBSOL | A solution is available

The solution status can be obtained by checking the XPRM_PBRES bits of the problem status. Possible values are:

XPRM_PBOPT | optimal solution found
XPRM_PBUNF | optimization unfinished
XPRM_PBINF | problem is infeasible
XPRM_PBUNB | problem is unbounded
XPRM_PBOTH | optimization failed (any other cause)
