Hi Ion, I have a class whose private members are string type of data. Each time i will create a new instance of my class and to each instance i will set some string type of data to it . After this i have to push this object it to the vector. Now i have a function called write_data which will take this vector list as input and will iterate through each vector element and push to shared memory vector . Now from this shared memory i have to iterate these objects and i have to get the string data present in these instance. Right now i am declaring this string type of data as boost::interprocess::string and will set this data to the instance of the class. But it will create segmentation fault when i am accessing this string type of data from the object when the size of string is more than 10. So is there any method to increase the buffer size of boost::interprocess::string .?
boost::interprocess::string is a normal string (indeed, from Boost 1.48
is a typedef for boost::container::string). To put it shared memory you
will need to use a shared memory allocator: you must use
boost::interprocess::basic_string
