Is there a better way than parsing /proc/self/maps to figure out memory protection?
I have a pointer and I want to check if the referenced memory is readable, writeable and/or executable. How can I do this?
You will have to parse the file
/proc/self/mapswhich contains memory mappings of your process, and check which of the mappings lie within the value of your pointer (if any). The/proc/self/mapsfile contains the memory protection (read/write/execute).See this question for more info about the maps file.
