Kako radi ova funkcija?

[ llux @ 14.05.2007. 19:50 ] @

Posto nisam ucio C nikako ne shvatam kako radi wsprintf funkcija:

Code:
TextOut (hdc, 22 * cxCaps + 40 * cxChar, cyChar * i, szBuffer,
wsprintf (szBuffer, TEXT ("%5d"),
GetSystemMetrics (sysmetrics[i].iIndex))) ;

Znam da brojeve koje vraca GetSystemMetrics funkcija wsprintf pretvara u text ali ne kapiram kako funkcionise.

Narocito me zbunjuje ono "%5d", sta je to? A takodje i sto szBuffer ne sadrzi nista a pojavljuje se pre wsprintf.

Ima li nesto drugo sto bih mogao da koristim? Nesto iz C++ mozda?

wsprinf pretvara / formatira duge tipove podataka u tekst.
Prvi argument je char* buffer , drugi simbolicno opisuje sta treba da se konvertuje a treci je ono sto treba da se konvertuje.
Ispod imas simbole sa drugi argument (iz win api helpa) uvek se pocinje sa % napr "%i" znaci da je treci argument int

c A single character. The wsprintf function ignores character arguments with a numeric value of zero. This sequence is interpreted as type WCHAR when the calling application uses the #define UNICODE compile flag and as type CHAR otherwise.
C A single character. This sequence is interpreted as type CHAR when the calling application uses the #define UNICODE compile flag and as type WCHAR otherwise.
d A signed decimal integer argument. This sequence is equivalent to the i sequence.
hc, hC A single character. The wsprintf function ignores character arguments with a numeric value of zero. This sequence is always interpreted as type CHAR, even when the calling application uses the #define UNICODE compile flag.
hs, hS A string. This sequence is always interpreted as type LPSTR, even when the calling application uses the #define UNICODE compile flag.
i A signed decimal integer. This sequence is equivalent to the d sequence.
lc, lC A single character. The wsprintf function ignores character arguments with a numeric value of zero. This sequence is always interpreted as type WCHAR, even when the calling application does not use the #define UNICODE compile flag.
ld A long signed decimal integer. This sequence is equivalent to the li sequence.
li A long signed decimal integer. This sequence is equivalent to the ld sequence.
ls, lS A string. This sequence is always interpreted as type LPWSTR, even when the calling application does not use the #define UNICODE compile flag. This sequence is equivalent to the ws sequence.
lu A long unsigned integer.
lx, lX A long unsigned hexadecimal integer in lowercase or uppercase.
s A string. This sequence is interpreted as type LPWSTR when the calling application uses the #define UNICODE compile flag and as type LPSTR otherwise.

u An unsigned integer argument.
