From 2528e47cb2131974a5274d32b41be34ac8cab19f Mon Sep 17 00:00:00 2001 From: Ruiyu Ni Date: Thu, 16 Jun 2016 11:12:53 +0800 Subject: [PATCH] ShellPkg: Use ".." to indicate device path is partially displayed The output of "dh " originally is like below: 12C: USBIO DevicePath(x0)/Pci(0x14,0x0)/USB(0x6,0x0)) The device path part is very confusing. Use ".." in front of the partially displayed device path is better and it also aligns to the example output in Shell spec. 12C: USBIO DevicePath(..)/Pci(0x14,0x0)/USB(0x6,0x0)) Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Ruiyu Ni Reviewed-by: Jiewen Yao Reviewed-by: Jaben Carsey --- ShellPkg/Library/UefiHandleParsingLib/UefiHandleParsingLib.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/ShellPkg/Library/UefiHandleParsingLib/UefiHandleParsingLib.c b/ShellPkg/Library/UefiHandleParsingLib/UefiHandleParsingLib.c index a81d1f208a..408199166d 100644 --- a/ShellPkg/Library/UefiHandleParsingLib/UefiHandleParsingLib.c +++ b/ShellPkg/Library/UefiHandleParsingLib/UefiHandleParsingLib.c @@ -753,6 +753,7 @@ DevicePathProtocolDumpInformation( CHAR16 *Temp; CHAR16 *Temp2; EFI_STATUS Status; + UINTN Size; Temp = NULL; Status = gBS->OpenProtocol(TheHandle, &gEfiDevicePathProtocolGuid, (VOID**)&DevPath, gImageHandle, NULL, EFI_OPEN_PROTOCOL_GET_PROTOCOL); @@ -765,7 +766,9 @@ DevicePathProtocolDumpInformation( } if (!Verbose && Temp != NULL && StrLen(Temp) > 30) { Temp2 = NULL; - Temp2 = StrnCatGrow(&Temp2, NULL, Temp+(StrLen(Temp) - 30), 30); + Size = 0; + Temp2 = StrnCatGrow(&Temp2, &Size, L"..", 0); + Temp2 = StrnCatGrow(&Temp2, &Size, Temp+(StrLen(Temp) - 28), 0); FreePool(Temp); Temp = Temp2; } -- 2.39.5
