Purpose
Loads directives into the current problem to specify which MIP entities the Optimizer should continue to branch on when a node solution is integer feasible.
Topic areas

Synopsis
int XPRS_CC XPRSloadbranchdirs(XPRSprob prob, int ncols, const int colind[], const int dir[]);
Arguments
prob 
The current problem.
ncols 
Number of directives.
colind 
Integer array of length ncols containing the column numbers. A negative value indicates a set number (the first set being -1, the second -2, and so on).
dir 
Integer array of length ncols containing either 0 or 1 for the entities given in colind. Entities for which dir is set to 1 will be branched on until fixed before an integer feasible solution is returned. If dir is NULL, the branching directive will be set for all entities in colind.
Further information
This function cannot be called while the current problem is being solved or when it is in an interrupted state. Use XPRSpostsolve to restore the problem to a non-solving state.
