Chapter 48. Embedded HTTP Server

The macro html_begin() generates an HTTP header with a "text/html" content type followed by an opening

"<html>" tag. html_end() generates a closing "</html>" tag and calls cyg_http_finish().

General HTML Support

void cyg_html_tag_begin( FILE *client, char *tag, char *attr );

void cyg_html_tag_end( FILE *client, char *tag );

#define html_tag_begin( __client, __tag, __attr )

#define html_tag_end( __client, __tag )

#define html_head( __client, __title, __meta )

#define html_body_begin( __client, __attr )

#define html_body_end( __client )

#define html_heading( __client, __level, __heading )

#define html_para_begin( __client, __attr )

#define html_url( __client, __text, __link )

#define html_image( __client, __source, __alt, __attr )

The function cyg_html_tag_begin() generates an opening tag with the given name. The function

cyg_html_tag_end() generates a closing tag with the given name. The macros html_tag_begin() and

html_tag_end are just wrappers for these functions.

The macro html_head() generates an HTML header section with __title as the title. The __meta argument

deﬁnes any meta tags that will be inserted into the header. html_body_begin() and html_body_end generate

HTML body begin and end tags.

html_heading() generates a complete HTML header where __level is a numerical level, between 1 and 6, and

__heading is the heading text. html_para_begin() generates a paragraph break.

html_url() inserts a URL where __text is the displayed text and __link is the URL of the linked page.

html_image() inserts an image tag where __source is the URL of the image to be included and __alt is the

alternative text for when the image is not displayed.

Table Support

#define html_table_begin( __client, __attr )

#define html_table_end( __client )

#define html_table_header( __client, __content, __attr )

#define html_table_row_begin( __client, __attr )

#define html_table_row_end( __client )

#define html_table_data_begin( __client, __attr )

#define html_table_data_end( __client )

html_table_begin() starts a table and html_table_end() end it. html_table_header() generates a simple

table column header containg the string __content.

html_table_row_begin() and html_table_row_end() begin and end a table row, and similarly

html_table_data_begin() and html_table_data_end() begin and end a table entry.
