	)

Reads data of an Online QP Benchmark problem from file. This function allocates the required memory for all data; after successfully calling it, you have to free this memory yourself!

Returns:: SUCCESSFUL_RETURN
RET_INVALID_ARGUMENTS
RET_UNABLE_TO_READ_FILE
RET_FILEDATA_INCONSISTENT

Parameters:

path	Full path of the data files (without trailing slash!).
nQP	Output: Number of QPs.
nV	Output: Number of variables.
nC	Output: Number of constraints.
nEC	Output: Number of equality constraints.
H	Output: Hessian matrix.
g	Output: Sequence of gradient vectors.
A	Output: Constraint matrix.
lb	Output: Sequence of lower bound vectors (on variables).
ub	Output: Sequence of upper bound vectors (on variables).
lbA	Output: Sequence of lower constraints' bound vectors.
ubA	Output: Sequence of upper constraints' bound vectors.
xOpt	Output: Sequence of primal solution vectors (not read if a null pointer is passed).
yOpt	Output: Sequence of dual solution vectors (not read if a null pointer is passed).
objOpt	Output: Sequence of optimal objective function values (not read if a null pointer is passed).
