Example: Printing the Current Directory

Program 2-6 implements a version of the UNIX command pwd. The MAX_PATH value is used to size the buffer, but an error test is still included to illustrate GetCurrentDirectory.

Program 2-6. pwd: Printing the Current Directory

/* Chapter 2. pwd -- Print working directory. */
#include "EvryThng.h"
#define DIRNAME_LEN MAX_PATH + 2
int _tmain (int argc, LPTSTR argv [])
{
TCHAR pwdBuffer [DIRNAME_LEN];
DWORD LenCurDir;
LenCurDir = GetCurrentDirectory (DIRNAME_LEN, pwdBuffer);
if (LenCurDir == 0) ReportError
(_T ("Failure getting pathname."), 1, TRUE);
if (LenCurDir > DIRNAME_LEN)
ReportError (_T ("Pathname is too long."), 2, FALSE);
PrintMsg (GetStdHandle (STD_OUTPUT_HANDLE), pwdBuffer);
return 0;
}
