We may want to extend the c/lib.c to override some of the most commonly used LibC operations, that StringZilla may be better equipped to handle. This includes:

  • memmem and memchr - definitely
  • memcpy, memmove, memset - possibly
  • memrchr - GNU extension for reverse-order memchr
  • memfrob - GNU extension with the sz_generate random generator

If we can afford a strlen call before the operation, several other APIs and GNU extensions can be replaced.
