XSLPsetdblcontrol

Purpose
Set the value of a double precision problem control
Synopsis
int XPRS_CC XSLPsetdblcontrol(XSLPprob prob, int control, double value);
Arguments
prob 
The current SLP problem.
control 
control (SLP or optimizer) whose value is to be returned.
value 
Double precision value to be set.
Example
The following example sets the value of the Xpress NonLinear control XSLP_CTOL and of the optimizer control XPRS_FEASTOL: 
XSLPsetdblcontrol(prob, XSLP_CTOL, 0.001);
XSLPgetdblcontrol(prob, XPRS_FEASTOL, 0.005);
Further information
Both SLP and optimizer controls can be set using this function. If an optimizer control is set, the return value will be the same as that from XPRSsetdblcontrol, which can similarly be used to set both Optimizer and SLP controls.
