Overwrite LibC symbols with `LD_PRELOAD` #102

Closed ashvardanian closed 5 months ago

ashvardanian commented 6 months ago

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.
