Function Documentation

◆ handle_forks()

pid_t handle_forks ( void )

Creates a child process using fork() and returns the process ID.

This function creates a child process using the fork() system call and returns the process ID for the child process.

Returns: Process ID of the child process or -1 on failure.

◆ handle_pipeline()

int handle_pipeline	(	int *	fildes,
		t_executor *	current,
		t_info *	info,
		int	i
	)

Handles the execution of a pipeline of commands.

This function manages the execution of multiple commands, including creating pipes, forking child processes, calling child and parent handlers and handling error conditions.

Parameters

fildes	Array of pipe file descriptors.
current	The current node of the executor list representing a command.
info	Pointer to the t_info structure.
i	Index of the current command/child in the pipeline.

Returns: OKAY on success, FAIL_SYSCALL/FAIL_SYSCALL_PARENT on failure.

◆ handle_pipes()

int handle_pipes ( int fildes[2] )

Creates a pipe and sets the file descriptors in the given array.

This function creates a pipe using the provided file descriptor array and sets the appropriate file descriptors for communication between commands.

Parameters

fildes Array to store pipe file descriptors.

Returns: 0 on success, -1 on failure.

◆ parent_handler_multi()

int parent_handler_multi	(	int *	fildes,
		t_executor *	current
	)

Handles the parent process during multi-command execution.

This function manages file descriptors for input and output redirection. It manages the pipe for the parent process.

Parameters

fildes	Array of pipe file descriptors.
current	The current node of the executor list representing a command.

Returns: OKAY on success, FAIL_SYSCALL on failure.
