[Help-glpk] Write Sensitivity Bounds

[address@hidden]

Hi all. 
As I am going to study a multiobjective problem, I need to 
explore Pareto Front with weighted sum method. To improve quality and 
speed of search it would be useful to get list of sensitivity bounds 
for objective coefficients of variables. 
If I "use 
lpx_print_sens_bnds" routine I get a file which is hard to read 
automatically with a program (I work with C/C++). 
Is there a way to 
get sensitivity bounds by API routines?

Thanks,
Claudio
