# XPRS_mse_getsollist

Purpose
Returns a list of solution ids of solutions found during the enumeration. The list is sorted by the value of some attribute of the solutions e.g., the MIP objective value.
Synopsis
`int XPRS_CC XPRS_mse_getsollist(XPRSmipsolenum mse, int iMetricId, int iRankFirstIndex, int iRankLastIndex, int iSolutionIds[], int * nReturnedSolIds, int * nSols)`
Arguments

mse | The current MIP solution enumerator.
iMetricId | Id of the attribute whose value is used to rank the solution ids returned in the iSolutionIds array e.g., the MIP objective value is used when MSE_METRIC_MIPOBJECT is passed down. A full list of all available attributes may be found in Chapter MSE Attributes, or from the list in the xprs.h header file.
iRankFirstIndex | Index (one-based) in the rank order of solutions for which the associated solution's id number, if there is a solution at this index, is to be returned in the first element of array iSolutionIds. If iRankLastIndex > iRankFirstIndex then any subsequent solutions in the rank ordering are to have their solution ids written to the subsequent elements of iSolutionIds.
iRankLastIndex | If iSolutionIds is non-NULL then at most iRankLastIndex - iRankFirstIndex + 1 solution ids will be written to iSolutionIds. There will be fewer solution ids written if iRankLastIndex is greater than the number of solutions registered in the MIP solution enumerator.
iSolutionIds | Integer array where the solution ids will be returned. May be NULL if not required.
nReturnedSolIds | Pointer to an integer where the number of solution ids that were available to be written is returned. This number will always be less than or equal to iRankLastIndex - iRankFirstIndex + 1. A value is returned for this parameter regardless of whether iSolutionIds is passed as NULL. May be NULL if not required.
nSols | Pointer to an integer where the total number of solution ids that could possibly be written is returned. May be NULL if not required.
