Detailed Description

Implementation of the InputBuffer and I/O functions.

Function Documentation

close_input_buffer()

void close_input_buffer

(

InputBuffer *

input_buffer

)

Frees the memory associated with an InputBuffer.

Parameters

[in]

input_buffer

The buffer to free. Must not be NULL.

Definition at line 72 of file inputbuffer.c.

Here is the caller graph for this function:

getline()

ssize_t getline	(	char **	lineptr,
		size_t *	n,
		FILE *	stream )

Reads an entire line from a stream into a dynamically resizing buffer.

Parameters

[in,out]	lineptr	Pointer to the character buffer pointer.
[in,out]	n	Pointer to the size of the allocated buffer.
[in]	stream	The file stream to read from (e.g., stdin).

Returns

The number of characters read, or -1 on EOF or error.

Here is the caller graph for this function:

new_input_buffer()

InputBuffer * new_input_buffer

(

void

)

Allocates and initializes a new InputBuffer.

Creates a fresh InputBuffer struct on the heap, setting its pointers to NULL and lengths to 0.

Returns

A pointer to the newly allocated InputBuffer.

Definition at line 9 of file inputbuffer.c.

read_input()

void read_input

(

InputBuffer *

input_buffer

)

Reads a line of input from standard input into the buffer.

Wraps getline to safely read from stdin. It also strips the trailing newline character and updates the input_length property. Exits the program automatically if reading fails.

Parameters

[in,out]

input_buffer

The buffer to read data into.
