In this code, when user inputs c:\temp, getcwd() returns "c:temp".

Actual path is C:Temp.

if(chdir(fullpath))
{
    perror("cd");
    return 1;
}
if(!getcwd(path, sizeof(char*) * 260))
{
    perror("getcwd error");
    getchar();
    exit(1);
}

I expected it to return "C:\Temp". Is there any way to get case-sensitive current working directory in C? Wherever I searched, there was only getcwd().
