MSDN에서 스플러의 정보를 받아오는 코딩부분을 바꾸고 있는데요...

아래와 같습니다.......

그런데 중간에 메모리 할당하는 부분인것 같은데

if( (pJobInfo = (JOB_INFO_1 *)malloc( dwNeeded )) == NULL )

이 부분을 어케 바꾸야 할지 모르겠네용 고수님덜 도와 주세용



BOOL ListJobsForPrinter( LPTSTR szPrinterName )

{

HANDLE hPrinter;

DWORD dwNeeded, dwReturned, i;

JOB_INFO_1 *pJobInfo;



// You need a printer handle, open the printer

if( ! OpenPrinter( szPrinterName, &hPrinter, NULL ) )

return FALSE;



// First you call EnumJobs() to find out how much memory you need

if( ! EnumJobs( hPrinter, 0, 0xFFFFFFFF, 1, NULL, 0, &dwNeeded,

&dwReturned ) )

{

// It should have failed, but if it failed for any reason other

// than "not enough memory", you should bail out

if( GetLastError() != ERROR_INSUFFICIENT_BUFFER )

{

ClosePrinter( hPrinter );

return FALSE;

}

}

// Allocate enough memory for the JOB_INFO_1 structures plus

// the extra data - dwNeeded from the previous call tells you

// the total size needed

if( (pJobInfo = (JOB_INFO_1 *)malloc( dwNeeded )) == NULL )

{

ClosePrinter( hPrinter );

return FALSE;

}

// Call EnumJobs() again and let it fill out our structures

if( ! EnumJobs( hPrinter, 0, 0xFFFFFFFF, 1, (LPBYTE)pJobInfo,

dwNeeded, &dwNeeded, &dwReturned ) )

{

ClosePrinter( hPrinter );

free( pJobInfo );

return FALSE;

}

// You're done with the printer handle, close it

ClosePrinter( hPrinter );



// dwReturned tells how many jobs there are

// Here, you'll simply display the number of jobs found

printf( "%d jobsn", dwReturned );

// It's easy to loop through the jobs and access each one

for(i=0;i
{

// pJobInfo[i] is a JOB_INFO_1 struct for that job

// so here you could do whatever you want for each job

printf( "[%d] [%s]n", pJobInfo[i].JobId, pJobInfo[i].pDocument );

}



// Clean up

free( pJobInfo );

return TRUE;
