cgi_parse_file_vars (

    FILE   *file,
    const char *prefix,
    size_t size)

Synopsis

Parses a CGI query string stored in a file, and loads the resulting variables into an existing symbol table, optionally prefixing each name with a string. Returns the number of variables loaded. The prefix can be NULL or empty if not required. The file data is assumed to be escaped (see http escape()); the data should not contain line breaks, spaces, or other unescaped chars. The file should already have been opened: a typical use for this function is to parse the values supplied in stdin. The maximum size for the file is CGI_QUERY_FILE_MAX characters.
