QsyFindNextValidationLstEntry()--Find Next Validation List Entry API

 #include <qsyvldl.h>

 int QsyFindNextValidationLstEntry
       (Qsy_Qual_Name_T        *Validation_Lst,
        Qsy_Entry_ID_Info_T    *Entry_ID,
        Qsy_Rtn_Vld_Lst_Ent_T  *Next_Entry);

The QsyFindNextValidationLstEntry() function finds the next entry in a validation list object after the entry that is passed in the Entry_ID parameter. It then returns the information for the next entry in the buffer that is pointed to by the Next_Entry parameter. The entries are stored in hexadecimal sort sequence; therefore, the next entry will be the one with an entry ID whose hexadecimal value would follow the hexadecimal value of the entry passed in the Entry_ID parameter. The entry specified in the Entry_ID parameter does not need to exist in the validation list, and this function does not have to follow a QsyFindFirstValidationLstEntry() or QsyFindValidationLstEntry() function call.

Authorities

Validation List Object

*USE

Validation List Object Library

*EXECUTE

Note: If the QsyEncryptData attribute is set to QSY_VFY_FIND_E (1), then the user must have *USE, *ADD, and *UPD authority to the validation list to get the data to be encrypted returned in the Next_Entry parameter.

Parameters

Validation_Lst

(Input)

A pointer to the qualified object name of the validation list to find the next entry in. The first 10 characters specify the validation list name, and the second 10 characters specify the library. You can use these special values for the library name:

*CURLIB	The current library is used to locate the validation list. If there is no current library, QGPL (general purpose library) is used.
*LIBL	The library list is used to locate the validation list.

Entry_ID

(Input)

A pointer to the entry ID information. The format of the Qsy_Entry_ID_Info_T structure is as follows:

int	Entry_ID_Len	The number of bytes of data that is provided as the entry ID. Possible values are from 1 through 100.
unsigned int	Entry_ID_CCSID	An integer that represents the CCSID for the entry ID. Valid CCSID values are in the range 0 through 65535. This value is not used to find the entry.
unsigned char	Entry_ID[100]	The data that is used to identify this entry in the validation list.

Next_Entry

(Output)

A pointer to the buffer where the next entry information is placed. The buffer must be allocated to the size of the Qsy_Rtn_Vld_Lst_Ent_T structure or the results will be unpredictable. The format of the Qsy_Rtn_Vld_Lst_Ent_T structure is as follows:

Qsy_Entry_ID_Info_T	Entry_ID_Info	The entry ID information structure.
Qsy_Entry_Encr_Data_Info_T	Encr_Data_Info	The data to be encrypted information structure.
Qsy_Entry_Data_Info_T	Entry_Data_Info	The entry data information structure.
char	Reserved[4]	This is an ignored field.
void *	Entry_More_Info	A pointer to additional information. This pointer is currently set to NULL.

See the Entry_ID parameter for the format of the Qsy_Entry_ID_Info_T structure.

The format of the Qsy_Entry_Encr_Data_Info_T structure is as follows:

int	Encr_Data_Len	The number of bytes of encrypted data that is stored in this validation list entry. If the QsyEncryptData attribute is 0 or the QRETSVRSEC system value is '0', the length will always be 0.
unsigned int	Encr_Data_CCSID	The CCSID associated with the encrypted data.
unsigned char	Encr_Data[600]	If the QsyEncryptData attribute is 1 and the QRETSVRSEC system value is '1', then the encrypted data that is stored in the entry will be decrypted and returned in this field. If the QsyEncryptData attribute is 0 or the QRETSVRSEC system value is '0', then the encrypted data cannot be returned, and the contents of this field are unpredictable.

The format of the Qsy_Entry_Data_Info_T structure is as follows:

int	Entry_Data_Len	The length of the entry data.
unsigned int	Entry_Data_CCSID	The CCSID associated with the entry data.
unsigned char	Entry_Data[1000]	The entry data.

Return Value

Error Conditions

If QsyFindNextValidationLstEntry() is not successful, errno indicates one of the following errors:

Example

The following example finds all the entries in the validation list object WEBUSRS.
