Kann mir jemand erklären was diese Funktion macht? Trotz kommentaren versteh ich nicht wie sie arbeitet
// Writes single record in configuration table // *buf --> Points to buffer which receives HTML // idx --> Index of current record (starting with zero) // Returns // Number of generated HTML bytes static int FS20_showrecord (UINT8 *buf, int idx) { static char *input_radio_start = "<INPUT TYPE=RADIO"; static char *input_text_start = "<INPUT TYPE=TEXT"; static char *input_end = ">"; static char *comment_start = " <!--"; static char *comment_mark = "°<!--"; static char *comment_learn = "<marquee>+</marquee><!--"; static char *comment_end = " -->"; // Dynamic char link[] = {0,0}; char *name = FS20_ee_readname(idx); char type = FS20_ee_readtype(idx); int idx3 = idx * 3; link[0] = FS20_ee_readlink(idx) + '0'; return sprintf ( buf, "<TR ALIGN=CENTER>" "<TH>" "%d" "</TH>" "<TD>" "%s NAME='%x' MAXLENGTH=20%s%s" "</TD>" "<TD>" "%s NAME='%x' MAXLENGTH=1 SIZE=1 VALUE='-'%s%s" "</TD>" "<TD>" "%s NAME='%x' VALUE='%x'%s" "</TD>" "<TD>" "%s NAME='%x' VALUE='%x'%s" "</TD>" "<TD>" "%s NAME='%x' VALUE='%x'%s" "</TD>" "</TR>", // Record number (1 is firts record) FS20_LINKNUMBER(idx), // Record name type == FS20_RT_EMPTY ? input_text_start : comment_start, WEB_FS20_TEXT, type == FS20_RT_EMPTY ? input_end : comment_end, type == FS20_RT_EMPTY ? "" : name, // Link type == FS20_RT_EMPTY ? input_text_start : comment_start, WEB_FS20_RECORDLINK, type == FS20_RT_EMPTY ? input_end : comment_end, type == FS20_RT_EMPTY ? "" : (link[0] == '0' ? "--" : link), // Learn WLAN radio button type == FS20_RT_EMPTY ? input_radio_start : (type == FS20_RT_WLAN ? comment_mark : (type == FS20_RT_LEARN_WLAN ? comment_learn : comment_start)), WEB_FS20_RADIO, WEB_FS20_RADIO + idx3, type == FS20_RT_EMPTY ? input_end : comment_end, // Learn RS232 radio button type == FS20_RT_EMPTY ? input_radio_start : (type == FS20_RT_RS232 ? comment_mark : (type == FS20_RT_LEARN_RS232 ? comment_learn : comment_start)), WEB_FS20_RADIO, WEB_FS20_RADIO + idx3 + 1, type == FS20_RT_EMPTY ? input_end : comment_end, // Release button type != FS20_RT_EMPTY ? input_radio_start : comment_start, WEB_FS20_RADIO, WEB_FS20_RADIO + idx3 + 2, type != FS20_RT_EMPTY ? input_end : comment_end ); }Und diese Makros sind mir auch suspekt
// Offset of field of FS20_RECORD #define FS20_FIELD_OFFSET(_field_) ((int)&(((FS20_RECORD *)0)->_field_)) // Base of FS20_RECORD in EEPROM #define FS20_RECORD_BASE(_num_) ((_num_)*sizeof(FS20_RECORD)) // Base of field of FS20_RECORD in EEPROM #define FS20_FIELD_BASE(_idx_,_name_) (EE_FS20RECORDS_BASE + FS20_RECORD_BASE(_idx_) + FS20_FIELD_OFFSET(_name_))Namen und Kommentare sind eindeutig, finde ich, aber ich verstehe die Arbeitsweise nicht.
Danke im Voraus.

kannst du vielleicht den ganzen code mitliefern??
was fehlt und was kann ich daraus lesen:/ Writes single record in configuration table // *buf --> Points to buffer which receives HTML // idx --> Index of current record (starting with zero) // Returns // Number of generated HTML bytes static int FS20_showrecord (UINT8 *buf, int idx)/* was ist UINT8 soll das ein unsignet int mit 8 bit sein man müsste schon sehen wo typedef angewant wird woher wass ungefaer bekommt idx*/ { //ist klar hier werden dann die variablen die dann über x = y ? z : a //zugeordnet werden ausgegeben static char *input_radio_start = "<INPUT TYPE=RADIO"; static char *input_text_start = "<INPUT TYPE=TEXT"; static char *input_end = ">"; static char *comment_start = " <!--"; static char *comment_mark = "°<!--"; static char *comment_learn = "<marquee>+</marquee><!--"; static char *comment_end = " -->"; // Dynamic char link[] = {0,0}; char *name = FS20_ee_readname(idx); //wo was macht diese methode char type = FS20_ee_readtype(idx);//und diese??? int idx3 = idx * 3; link[0] = FS20_ee_readlink(idx) + '0';//und diese??? return sprintf ( buf, //das folgende wird in buf gescrieben und der ganze block wird returned "<TR ALIGN=CENTER>" "<TH>" "%d" "</TH>" "<TD>" "%s NAME='%x' MAXLENGTH=20%s%s" "</TD>" "<TD>" "%s NAME='%x' MAXLENGTH=1 SIZE=1 VALUE='-'%s%s" "</TD>" "<TD>" "%s NAME='%x' VALUE='%x'%s" "</TD>" "<TD>" "%s NAME='%x' VALUE='%x'%s" "</TD>" "<TD>" "%s NAME='%x' VALUE='%x'%s" "</TD>" "</TR>", // Record number (1 is firts record) FS20_LINKNUMBER(idx),//wo ist diese methode // Record name type == FS20_RT_EMPTY ? input_text_start : comment_start,//wieso ==??????
