string_append_literal

#define string_append_literal	(		x,
			y
	)		string_append_with_size(x, y, (sizeof y) - 1)

Function Documentation

generate_html_table()

void generate_html_table	(	struct string *	robot_grid,
		const int	x_max,
		const int	y_max,
		const int	x_coord,
		const int	y_coord
	)

Generates the HTML table with the robot in the good case from given coordinates.

Parameters

robot_grid	Pointer for the result.
x_max	Value max for x (so number of lines in the grid - 1).
y_max	Value max for y (so number of columns in the grid - 1).
x_coord	Robot's x coordinate.
y_coord	Robot's y coordinate.

parse_client_request()

void parse_client_request	(	const char *	client_request,
		size_t	data_len,
		char *	method,
		char *	path,
		char *	version,
		int *	p_cookie_x,
		int *	p_cookie_y,
		int *	p_cookie_found
	)

Parses a client request and gets all needed information:

From the first line of the request:

• method (e.g. GET, POST…)
• path (e.g. /data/template.css)
• HTTP version (e.g. HTTP/1)

From the cookies:

• Are there cookies or not ?
• If yes, x and y coordinates of robot.

Parameters

client_request	Pointer to the client's request string.
data_len	Size of client's request.
method	Pointer for the method (initialze with char method[16];).
path	Pointer for the path. (initialze with char path[1024];).
version	Pointer for the version (initialze with char version[16];).
p_cookie_x	Pointer for the x coordinate in the cookies.
p_cookie_y	Pointer for the y coordinate in the cookies.
p_cookie_found	Pointer for a boolean to know if there is a cookie: 1 if cookie was found, otherwise 0.

templates_deinit()

void templates_deinit

(

struct templates *

p_tem

)

Frees (de-initializes) memory used by a template structure.

Parameters

p_tem

Pointer to the template structure to de-initialize.

templates_init()

void templates_init

(

struct templates *

p_tem

)

Initializes a template structure by opening and reading all files.

Uses the open_and_read() function from base64.h.

Parameters

p_tem

Pointer to the template structure to initialize.
