atol() won't work

[William Rizzo]

Hi there,

I'm not so deep in programming...

my need is to convert a string to a long int...
generally i use atol();
but it won't work. i'm trying so:
snmp_set_quick_print(1);
value = atol((vars->name, vars->name_length, vars));

is this correct?

i receive a well formatted output using print_value(), but i need to manipulate the data with mathematical expressions....

Can someone help me?

Thanks

William
