cwbSV_GetErrFileName

Purpose

Returns the message file name for the top-level (the. most recent) message added to the error handle provided. This message attribute only pertains to messages returned from the iSeries™ server. The file name is the name of the iSeries server message file that contains the message.

Syntax

 
unsigned int CWB_ENTRY cwbSV_GetErrFileName(
                             cwbSV_ErrHandle  errorHandle,
                             char            *fileName,
                             unsigned long    fileNameLength,
                             unsigned long   *returnLength);

Parameters

cwbSV_ErrHandle errorHandle - input

Handle that was returned by a previous call to the cwbSV_CreateErrHandle() API.

char * fileName - input/output

Pointer to a buffer that will receive the message file name stored in the error identified by the handle. The value returned is an ASCIIZ string.

unsigned long fileNameLength - input

Length of the receive buffer passed in. It should include space for the terminating null character. If the buffer is too small, the value will be truncated and CWB_BUFFER_OVERFLOW and returnLength will be set. NOTE: The recommended size is CWBSV_MAX_MSGFILE_NAME.

unsigned long * returnLength - input/output

Optional, may be NULL. A return address to store the number of bytes needed to hold the output string if the receive buffer is too small.

Return Codes

The following list shows common return values.

CWB_OK

Successful completion.

CWB_BUFFER_OVERFLOW

Output buffer too small, data truncated.

CWB_INVALID_POINTER

NULL passed on output parameter.

CWB_INVALID_HANDLE

Invalid handle.

CWBSV_NO_ERROR_MESSAGES

No messages are in the error handle.

CWBSV_ATTRIBUTE_NOT_SET

Attribute not set in current message.

Usage

iSeries server messages may be added to the error handle when using the cwbRC_CallPgm() and cwbRC_RunCmd() API's. In these cases, you can use this API to retrieve the message file name for the iSeries server messages contained in the error handle. If there is no message file name attribute for the message, return code CWBSV_ATTRIBUTE_NOT_SET will be returned.
