The pointer to the CPLEX environment as returned by CPXopenCPLEX()
.
An integer value indicating the optimization algorithm from which the user-written callback function was called. The parameter wherefrom
MUST be the value of wherefrom
passed to the user-written callback function. See CPXgetlpcallbackfunc
()
for possible values of wherefrom
and their meaning.
