Going thorugh overflow function documentation. I found overflow has following as return values.
Return Value:
A value different than EOF (or traits::eof() for other traits) signals success.
If the function fails, either EOF (or traits::eof() for other traits) is returned or an exception is thrown.
source :”http://www.cplusplus.com/reference/iostream/streambuf/overflow/“
Can anyone please tell me in which sceanrios is overflow function going to through an exception?
Any help will be appreciated
In my problematic scenario it was faling because it was not jumping the next address(setp calls was incrementating by 0) so retrying to use the same memory region and was giving segmentation fault.
