Detailed Description

A class to store the information of a memory segment.

This class stores the information of one memory segment in a way it is given in /proc/PID/maps file. It uses its own style of storing the permissions though.

Member Function Documentation

◆ DecodePermissions()

uint8_t SegmentInfo::DecodePermissions ( const std::string & permissions )

noexcept

Get permissions stored to mode_ field from std::string.

Parameters

[in] permissions Permissions stored as std::string, for example, "rwxp". Some additional characters after are not prohibited.

Returns: Exit code, 0 is success, 1 is failure.

Store permissions of a memory segment from std::string to mode_ field. In case of an error permissions are not stored and 1 is returned.

◆ EncodePermissions()

std::string SegmentInfo::EncodePermissions ( ) const

noexcept

Get permissions stored as std::string processed from the mode_ field.

Returns: Permissions stored as std::string, for example, "rwxp".

Process permissions of a memory segment from the mode_ field to std::string.

Inode ID if it is a file mapping (e.g., executable from

◆ mode_

uint8_t SegmentInfo::mode_ {0}

is 1 (private - shared)

Permissions, are stored as 0000rwx(p/s), where p is 0, s

◆ offset_

size_t SegmentInfo::offset_ {0}

(e.g., executable from ROM)

Offset from the start of the file if it is a file mapping
