### /Lb Compiler Option

Syntax: | Default:
/Lb[+|-] | /Lb-

Use /Lb to include a table in the listing file that shows all the struct and union variables in the source program. The table shows how each structure and union in the program is mapped. It contains the following information:

- The name of the structure or union and the elements within each.
- The byte offset of each element from the beginning of the structure or union. The bit offset for unaligned bit data is also given.
- The length of each element.
- The total length of each structure, union, and substructure in both packed and unpacked formats.

By default, the listing file does not include a layout.
