# XPRSaddcbnodelpsolved

Purpose

This callback function will be called in addition to any callbacks already added by XPRSaddcbnodelpsolved.

Synopsis
`int XPRS_CC XPRSaddcbnodelpsolved(XPRSprob prob, void (XPRS_CC *nodelpsolved)(XPRSprob cbprob, void *cbdata), void *data, int priority);`
Arguments

prob | The current problem.
nodelpsolved | The callback function, which takes arguments cbprob and cbdata, and has no return value.
cbprob | The problem passed to the callback function, nodelpsolved.
cbdata | The user-defined data passed as data when setting up the callback.
data | A user-defined data to be passed to the callback function, nodelpsolved.
