memx-cdy

c interface of memx: the fast memory functions like a libc memcmp(), memchr(), memmem(), memcpy(), memset()

Features

• Faster os libc and musl libc
• Replace dynamic os libc using LD_PRELOAD

Quick install

1. you can install this into cargo lib path:

text cargo build --release mkdir -p $HOME/.cargo/lib cp -a target/release/libmemx_cdy.so target/release/libmemx_cdy.a $HOME/.cargo/lib

1. you can build debian package:

text cargo deb

and install .deb into your local repository of debian package.

Usage

Easy to use, LD_PRELOAD.

1. usecase: cargo install text $ LD_PRELOAD=~/.cargo/lib/libmemx_cdy.so command

or

text $ export LD_PRELOAD=~/.cargo/lib/libmemx_cdy.so

1. usecase: debian package

text $ LD_PRELOAD=/usr/lib/libmemx_cdy.so.0.1 command

or

text $ export LD_PRELOAD=/usr/lib/libmemx_cdy.so.0.1

The memx benchmark results

• memchr() - map to c memchr()
• memcmp() - map to c memcmp()
• memcpy() - map to c memcpy()
• memeq() - map to c bcmpr()
• memmem() - map to c memmem()
• memset() - map to c memset()
