What i want to know is when and why this happens. From what i understand, cc is in debug. Please consider the below scenario:
I have a header file and its corresponding source file:
So you can see the pattern 0xcdcdcdcd when you read data from a dynamic heap. While debugging, this shows 0xcdcdcdcd {thedouble=??? The constant 0xcd is used by microsoft c++ debug libraries to fill allocated heap blocks. In a simple console application i am trying to read a file containing a hex value on each line.
I was grabbing the wrong value for comparison, the cdcdcdcd was coming from somewhere else. }so i know my variable isnt getting stored in my mutator. Exmp.h (header file) exmp.cpp (source file) in the header file i have a function. When is this specific to the.
00000084`67b96d50 cdcdcdcd cdcdcdcd 67b96dd8 00000084 as far as i know, 0xcdcdcdcd cdcdcdcd is special values on heap when program is compiled with debug option.
@angryinsomniac writing cdcdcdcd would help people see that a block is likely unallocated, but it would be incorrect for any code to look for cdcdcdcd to determine if. It works for the first few, but after 4 or 5 it starts outputting cdcdcdcd. I'm confused as to what i'm doing wrong?
