pScanInfo->last_file_path3的内容为什么有时显示不正常
在一个小系统的嵌入式平台上, pScanInfo->last_file_path3的内容为什么有时显示不正常？
是小系统的问题吗?

__bool ScanGetLastFile(HSCAN hScan, eBookScanedEntry_t* return_enter1,eBookScanedEntry_t* return_enter2,eBookScanedEntry_t* return_enter3, __s32 *nNandFileCount)
{

if(hScan == NULL || return_enter1== NULL || return_enter2 == NULL || return_enter3== NULL)
{
//eLIBs_printf("..%s..%d.....\n", __FILE__, __LINE__);
return EPDK_FALSE;
}

pScanInfo = (eBookScanInfo_t*)hScan;
if(pScanInfo->CurCnt == 0)
{
return EPDK_FALSE;
}

*nNandFileCount = pScanInfo->CurCnt;

eLIBs_printf("..%s..%d...pScanInfo->CurCnt=%d...path = %s;...path = %s;...path = %s;\n\n", __FILE__, __LINE__,

[解决办法]

*nNandFileCount = pScanInfo->CurCnt;

eLIBs_printf("..%s..%d...pScanInfo->CurCnt=%d...path = %s;...path = %s;...path = %s;\n\n", __FILE__, __LINE__, 
pScanInfo->CurCnt, pScanInfo->last_file_path1, pScanInfo->last_file_path2, pScanInfo->last_file_path3);
//pScanInfo->last_file_path1, pScanInfo->last_file_path2, pScanInfo->last_file_path3 内容显示正常

上面的注释里，你声称程序到这里为止一直是正常的，那么后面如果出现不正常，妥妥是因为eLIBs_printf的问题，除非你上面的注释里是胡扯的。
