UNIX
If you plan to port your programs to UNIX, follow these guidelines:
Don't remove header files from the SYS subdirectory. You can place the SYS header files elsewhere only if you don't plan to transport your programs to UNIX.
Use the UNIX-compatible path delimiter in routines that take strings representing paths and filenames as arguments. UNIX supports only the forward slash (/) for this purpose, but Win32 operating systems support both the backslash (\) and the forward slash (/). This documentation uses UNIX-compatible forward slashes as path delimiters in
#include
statements, for example. (However, the Windows operating system command shell, CMD.EXE, doesn't support the forward slash in commands entered at the command prompt.)Use paths and filenames that work correctly in UNIX, which is case-sensitive. The file allocation table (FAT) file system in Win32 operating systems isn't case-sensitive. The NTFS file system preserves case for directory listings, but ignores case in file searches and other system operations.
Note
In this version of Visual C++, UNIX compatibility information has been removed from the function descriptions.
