Function Documentation

process_output_char()

static void process_output_char ( t_ui *  ui, char  c, char *  line, int *  line_len  )

static

Process 1 output character from the child pipe into line buffers.

• On \n it flushes the current line to out_add_line() & resets len
• Otherwise it appends c to line if below BUF_SIZE - 2

Parameters

ui	UI state
c	Character read from the pipe
line	Working buffer (accumulates the current line)
line_len	Pointer to the current position in the line

read_output_from_fd()

void read_output_from_fd	(	t_ui *	ui,
		int	fd
	)

Read all available bytes from fd and split into output lines.

Reads in chunks of BUF_SIZE and any unterminated line is flushed after EOF

Parameters

ui	UI states
fd	File descriptor to read from (pipe read end)

Full pipeline inside the UI.

tokenize -> expand_all_tokens -> parse -> collect_heredocs -> executor

Parameters

input	Command string to execute
shell	Shell state (provides environment and execution context)

Returns

Exit status of the command, 1 on expand error, 2 on failure and 130 on heredoc interruption
