Introduction

• Refer to pictures in Pipes and Case Study: IPC (Parent/Child) Over Unnamed Pipe

• Scenario

  • Database inserts from stdin (svnr, firstname, lastname), some c++ trickery to split. auto [svrn, firstname, lastname] = read_record();

  • SIGUSR1: commit+log+debug request asynchronously (by the auditor?)

  • SIGUSR2:

• Start with read_record(STDIN_FILENO), and wonder how to react on signals

  • Introduction

  • Async-Signal-Safety

  • Use Case: Self-Pipe Trick

and check on EINTR?
