Question

I structures like the following

typedef struct 
{

    char *ptr;

    size_t used;
    size_t size;

} buffer;

typedef struct 
{

    buffer *request;
    buffer *uri;

    buffer *orig_uri;

    http_method_t  http_method;
    http_version_t http_version;

    buffer *request_line;

    /* strings to the header */
    buffer *http_host; /* not alloced */
    const char   *http_range;
    const char   *http_content_type;
    const char   *http_if_modified_since;
    const char   *http_if_none_match;

    array  *headers;

    /* CONTENT */
    size_t content_length; /* returned by strtoul() */

    /* internal representation */
    int     accept_encoding;

    /* internal */
    buffer *pathinfo;
} request;

Now if I want to write(in a text file) the value of the member “http_host” which belongs to the structure “request”. The member “http_host” is actually a “buffer” type, how should I write it? Kindly explain with the syntax.

Have you tried something like this?

// open the file
FILE *fp = fopen("myfile.txt");

// print
fprintf(fp, "%s\n", http_host->ptr);

// close the file
fclose(fp);
