Welcome to string_lib_asm, a collection of assembly language helper functions, offering functionality that closely parallels the string manipulation capabilities found in the C standard library string.h.

The library implements the following functions:

• strlen as my_strlen
• strchr as my_strchr
• memset as my_memset
• memcpy as my_memcpy
• strcmp as my_strcmp
• memmove as my_memmove
• strncmp as my_strncmp
• strcasecmp as my_strcasecmp
• index as my_index
• read as my_read
• write as my_write

Each function is contained within its own .S file. The automated build process creates an executable program as well as static and dynamic libraries.

This program will only compile on Linux systems with an X86-64 architecture. To compile the library and its components, run the Makefile from the project repository.

Compile:

make

Clean up:

make fclean

The static and dynamic libraries can be used with any C program on Linux systems with X86-64 architecture.

Within the my_libasm program, each assembly function is callable from a corresponding C function, with a standardized naming convention, e.g., asm_strlen() in C calls my_strlen() in assembly.

Run the unit tests for each function via the main() in my_libasm.c:

./my_libasm
