This repository contains standalone programs to demonstrate a feature or concept.

For assembly and systems programming concepts, refer to my sheharyaar/systems-assembly repository.

1. unshare

   1. unshare-files: demonstrates CLONE_FILES flag for unshare. This flag creates a seperate copy of descriptor table so that the other processes doen't affect the file descriptors on this one.
   2. unshare-fs: demonstrates CLONE_FS flag for unshare. This flag seperates current working directory, directory attributes, etc. from other processes.
   3. unshare-pid: demonstrates CLONE_NEWPID flag for unshare. This flag creates the first child process to pid 1 which acts as init for that namespace.

2. gcc-attributes

   1. constructor.c: demonstrated the use of constructor and destructor GCC attributes.
   2. constructor-hook.c: expands on the previous example to use constructor with LD_PRELOAD to hook libc function.
   3. noreturn.c: demonstrates noreturn GCC attribute and C11 feature.
   4. unused.c: demonstrates unused GCC attribute.

3. golang

   1. init-func.go: demonstrates the use of init function in Go.
   2. multiple-return-values.go: demonstrates the use of multiple return values in Go.
   3. struct-tags.go: demonstrates the use of struct tags in Go.
   4. json-structs.go: demonstrates the use of JSON structs in Go.
   5. happpens-before.go: demonstrates the concurrency concept of happens-before in Go.
