|
|
|
+ * Represents executable data that may be loaded into a kernel process.
|
|
|
+ *
|
|
|
+ * A code set consists of three basic segments:
|
|
|
+ * - A code (AKA text) segment,
|
|
|
+ * - A read-only data segment (rodata)
|
|
|
+ * - A data segment
|
|
|
+ *
|
|
|
+ * The code segment is the portion of the object file that contains
|
|
|
+ * executable instructions.
|
|
|
+ *
|
|
|
+ * The read-only data segment in the portion of the object file that
|
|
|
+ * contains (as one would expect) read-only data, such as fixed constant
|
|
|
+ * values and data structures.
|
|
|
+ *
|
|
|
+ * The data segment is similar to the read-only data segment -- it contains
|
|
|
+ * variables and data structures that have predefined values, however,
|
|
|
+ * entities within this segment can be modified.
