Syntax BOOL EnumJobs( __in HANDLE hPrinter, __in DWORD FirstJob, __in DWORD NoJobs, __in DWORD Level, __out LPBYTE pJob, __in DWORD cbBuf, __out LPDWORD pcbNeeded, __out LPDWORD pcReturned ); Parameters hPrinter [in] A handle to the printer object whose print jobs the function enumerates. Use the OpenPrinter or AddPrinter function to retrieve a printer handle. FirstJob [in] The zero-based position within the print queue of the first print job to enumerate. For example, a value of 0 specifies that enumeration should begin at the first print job in the print queue; a value of 9 specifies that enumeration should begin at the tenth print job in the print queue. NoJobs [in] The total number of print jobs to enumerate. Level [in] The type of information returned in the pJob buffer. ValueMeaning 1pJob receives an array of JOB_INFO_1 structures 2pJob receives an array of JOB_INFO_2 structures 3pJob receives an array of JOB_INFO_3 structures pJob [out] A pointer to a buffer that receives an array of JOB_INFO_1, JOB_INFO_2, or JOB_INFO_3 structures. The buffer must be large enough to receive the array of structures and any strings or other data to which the structure members point. To determine the required buffer size, call EnumJobs with cbBuf set to zero. EnumJobs fails, GetLastError returns ERROR_INSUFFICIENT_BUFFER, and the pcbNeeded parameter returns the size, in bytes, of the buffer required to hold the array of structures and their data. cbBuf [in] The size, in bytes, of the pJob buffer. pcbNeeded [out] A pointer to a variable that receives the number of bytes copied if the function succeeds. If the function fails, the variable receives the number of bytes required. pcReturned [out] A pointer to a variable that receives the number of JOB_INFO_1, JOB_INFO_2, or JOB_INFO_3 structures returned in the pJob buffer. Return Value If the function succeeds, the return value is a nonzero value. If the function fails, the return value is zero. Remarks The JOB_INFO_1 structure contains general print-job information; the JOB_INFO_2 structure has much more detailed information. The JOB_INFO_3 structure contains information about how jobs are linked. To determine the number of print jobs in the printer queue, call the GetPrinter function with the Level parameter set to 2.
