Detailed Description

A table of densely packed, null-terminated strings indexed by offset.

This table abstracts a densely concatenated list of null-terminated strings, each of which can be referenced using an offset into the table.

This requires and ensures that the string at offset 0 is also the empty string. This helps allow zero-initialized offsets form empty strings and avoids non-zero initialization when using a string literal pointer would allow a null pointer.

The primary use case is having a single global string literal for the table contents, and offsets into it in other global data structures to avoid dynamic relocations of individual string literal pointers in those global data structures.
