# getname

Purpose
Get the name of a decision variable or constraint of the problem.
Synopsis
`function getname(x:mpvar):string`
`function getname(c:linctr):string`
`function getname(nl:nlctr):string`
`function getname(lc:logctr):string`
Arguments

x | A decision variable used in the problem
c | A constraint (or SOS) of the problem
nl | A non linear constraint of the problem
lc | A logical constraint

Return value
Name of the given object.
Further information
1. This function returns the name of a decision variable or constraint of the problem that would be used for matrix exportation. The parameter of this function must be part of the problem — for instance a hidden constraint cannot be assigned a name.
2. This function requires that the matrix has been generated ( e.g. by a call to exportprob or loadprob). When used with a non linear constraint it is further required for the problem to be loaded into the optimiser and the parameter XPRS_loadnames must be true.
