GRBgetstrattr

int	GRBgetstrattr (	GRBmodel	*model,
		const char	*attrname,
		char	**valueP )

Query the value of a string-valued model attribute.

Return value:

A non-zero return value indicates that a problem occurred while querying the attribute. Refer to the Error Code table for a list of possible return values. Details on the error can be obtained by calling GRBgeterrormsg.

Arguments:

model: A loaded optimization model, typically created by routine GRBnewmodel or GRBreadmodel.

attrname: The name of a string-valued model attribute. Available attributes are listed and described in the Attributes section of this document.

valueP: The location in which the current value of the requested attribute should be placed.

Important note:

Note that all interface routines that return string-valued attributes are returning pointers into internal Gurobi data structures. The user should copy the contents of the pointer to a different data structure before the next call to a Gurobi library routine. The user should also be careful to never modify the data pointed to by the returned character pointer.

Example usage:

  char *modelname;
  error = GRBgetstrattr(model, "ModelName", &modelname);
