The IDA Pro Book, 2nd Edition

Using Standard Structures

As mentioned previously, IDA recognizes a tremendous number of data structures associated with various library and API functions. When a database is initially created, IDA attempts to determine the compiler and platform associated with the binary and loads the structure templates derived from related library header files. As IDA encounters actual structure manipulations in the disassembly, it adds the appropriate structure definitions to the Structures window. Thus, the Structures window represents the subset of known structures that happen to apply to the current binary. In addition to creating your own custom structures, you can add additional standard structures to the Structures window by drawing from IDA’s list of ...
