Problem Information
Synopsis
`int XPRS_CC XPRSgetrowflags(XPRSprob prob, int flags[], int first, int last);`
Arguments

prob | The current problem
flags | Integer array of length last-first+1 where type of information (see below) will be returned
first | First row index to be checked
last | Last row index to be checked

Example
The following example will print all three messages if the row at index 1 of the problem is an indicator constraint involving a quadratic matrix:

    int flags[2];
    ...
    XPRSgetrowflags(prob,1,2,flags);
    if (flags[0] & (XPRS_ROWFLAG_QUADRATIC)) { printf("the second row is quadratic" }
    if (flags[0] & (XPRS_ROWFLAG_INDICATOR)) { printf("the second row is an indicator" }
    if (flags[0] & (XPRS_ROWFLAG_QUADRATIC+XPRS_ROWFLAG_INDICATOR)) { printf("the second row is a quadratic indicator" }

Further information
The flags array returns a bitvector for each row defining all the information that is currently attached to that row:

XPRS_ROWFLAG_QUADRATIC
  The row has quadratic coefficients.
XPRS_ROWFLAG_DELAYED
  The row is marked as a delayed row.
XPRS_ROWFLAG_MODELCUT
  The row is marked as a model cut.
XPRS_ROWFLAG_INDICATOR
  The row is used as an indicator.
XPRS_ROWFLAG_NONLINEAR
  The row has nonlinear coefficients.
