How to convert char to int??



DATETIME dt;
REQUEST_DATEANDTIME_GET(SYNC,&dt);

I want convert the dt.date to int

[adrian_diesel]

//char * to int
int atoi( char* pStr ) 
{ 
  int iRetVal = 0; 
  int iTens = 1;
 
  if ( pStr )
  {
	char* pCur = pStr; 
	while (*pCur) 
	  pCur++;
 
	pCur--;
 
	while ( pCur >= pStr && *pCur <= '9' && *pCur >= '0' ) 
	{ 
	  iRetVal += ((*pCur - '0') * iTens);
	  pCur--; 
	  iTens *= 10; 
	}
  } 
  return iRetVal; 
}

AND THE CHAR HOW TO CONVERT STRID

[hel2o]

void settime(char time,wchar_t* filename)
{
  int f;
  char buf[4];
  wchar_t wstring[4];
  snwprintf(wstring,4,L"%d",time);
  wstr2strn(buf, wstring,20);
  f = _fopen(L"/tpa/preset/system/settings",filename, 0x204,0x180, 0);
  fwrite(f,buf,20);
  fclose(f);
}

STRID gettime(wchar_t *filename)
{
  int f;
  STRID timed;
  f = _fopen(L"/tpa/preset/system/settings",filename, 0x108,0x180, 0);
  FSTAT fs;
  fstat(L"/tpa/preset/system/settings",filename,&fs);
  char buf[8];
  wchar_t wstr[16];
  memset(buf, 0, 8);
  buf[fread( f, buf,fs.fsize)]=0;
  fclose(f);
  str2wstr(wstr, buf);
  timed=Str2ID(wstr,0,SID_ANY_LEN);
  return timed;
}

int main (void)
{
  DATETIME dt;
  REQUEST_DATEANDTIME_GET(SYNC,&dt);

  settime(dt.time.sec, L"s.bin");
  

  wchar_t ws[8];

  
  snwprintf(ws,8,L"%d",(dt.time.sec//this char - gettime(L"s.bin")//this STRID));//How to convert this STRID  to CHAR and then get them the difference's value and then MessageBox??

  MessageBox( EMPTY_SID,Str2ID(ws,0,SID_ANY_LEN),0xffff,1,0,0);

This might help. It will convert the string to char and display the two values in the message box.
But I don`t know how to get the difference between the two so you might have to convert to int using adrian_diesels method.

Spoiler

TEXTID timed;// moved so it can be accessed by main
void settime(int time,wchar_t* filename)
{
int f;
char buf[4];
wchar_t wstring[4];
snwprintf(wstring,4,L"%d",time);
wstr2strn(buf, wstring,20);
f = _fopen(L"/tpa/preset/system/settings",filename,0x204,0x180, 0);
fwrite(f,buf,20);
fclose(f);
}

TEXTID gettime(wchar_t *filename)
{
int f;
f = _fopen(L"/tpa/preset/system/settings",filename, 0x108,0x180, 0);
FSTAT fs;
fstat(L"/tpa/preset/system/settings",filename,&fs);
char buf[8];
wchar_t wstr[16];
memset(buf, 0, 8);
buf[fread( f, buf,fs.fsize)]=0;
fclose(f);
str2wstr(wstr, buf);
timed=TextID_Create(wstr,ENC_UCS2,TEXTID_ANY_LEN);
return timed;
}

int main (void)
{
DATETIME dt;
REQUEST_DATEANDTIME_GET(SYNC,&dt);

settime(dt.time.sec, L"s.bin");
gettime(L"s.bin");

wchar_t bs[8];                  //convert timed to wchar_t
TextID2wstr (timed, bs, 100);

wchar_t ws[8];
snwprintf(ws,8,L"%d-%ls",dt.time.sec,bs);
MessageBox( EMPTY_TEXTID,TextID_Create(ws,ENC_UCS2,TEXTID_ANY_LEN),0xffff,1,0,0);

  return(0);
}

Out of curiosity, what is it that you are trying to do overall?

Get phone running time

Have you tried looking at the source for breakcountdown v1.0 elf by stonos?  At a glance it seems to perform checks against the current time.  Might be helpful but I haven`t looked at it properly yet.
