Break Down the Problem

1. Identify the POSIX functions related to signal handling.
2. List functions that allow the association of signals with custom handlers.

Relevant Concepts

1. sigaction: A function that examines or specifies the action to be associated with a specific signal.
2. kill: A function used to send a signal to a process or a group of processes.
3. signal: An alternative function to specify a signal handler for a particular signal.
4. sigemptyset/sigfillset: Functions used to initialize signal sets, but not directly related to associating signal handlers.

Analysis and Detail

1. The function sigaction is the most commonly used POSIX function for associating a signal with a custom handler. It allows the programmer to define how a program should respond to a specific signal.
2. The signal function can also be used for simpler use cases of signal handling to assign a signal handler.

Verify and Summarize

The relevant POSIX functions for associating a signal with a custom handler are:

1. sigaction: For setting up a new signal handler.
2. signal: An older method for assigning a signal handler.

Final Answer

The POSIX functions that can be used to associate a signal with a custom handler are sigaction and signal.
