The purpose of this project is to code a small data exchange program using UNIX signals.
Mandotary Part external functs.
| Function | Description |
|---|---|
| ft_printf | Implements a custom printf-like function, creating formatted output. |
| signal | Used to catch a specific signal and perform a specified action when the signal is received. |
| sigemptyset | Clears a signal set, used in signal handling to clear the signal set. |
| sigaddset | Adds a signal to a signal set, used in signal handling to add one or more signals to the signal set. |
| sigaction | Used to define a custom action for a specific signal. Specifies a function to be called when the signal is received. |
| kill | Used to terminate a specified process or send a specific signal. Often used for interprocess communication. |
| getpid | Returns the Process ID (PID) of the current process. |
| malloc | Used for memory allocation. Allocates dynamic memory of a specified size and returns the starting address. |
| free | Releases previously allocated dynamic memory. Allows returning allocated memory to the system. |
| pause | Temporarily suspends a process and waits until a specified signal is received. Often used for signal waiting. |
| sleep | Sleeps the process for a specified duration in seconds. The process remains idle for the specified time. |
| usleep | Sleeps the process for a specified duration in microseconds (milliseconds). Pauses the process for a brief period. |
| exit | Terminates the process and exits, optionally returning an exit code. Typically used for ending a program. |
The client takes two parameters:
◦ The server PID.
◦ The string to send.Bonus Part
- The server acknowledges every message received by sending back a signal to the client.
- Unicode characters support! < I have done >
