This function gives you the list of invalid chars for a filename. Up to you to check that your filename doesn't contain any:

public static char[] Path.GetInvalidFileNameChars()

Docs here.

Note that if you want to validate a directory name, you should use GetInvalidPathChars().

EDIT: Oooops! Sorry, I thought you were on .NET. Using Reflector, here's what this functions boils down to:

'"', '<', '>', '|', 
'\0', '\x0001', '\x0002', '\x0003', '\x0004', '\x0005', '\x0006', 
'\a', '\b', '\t', '\n', '\v', '\f', '\r', 
'\x000e', '\x000f', '\x0010', '\x0011', '\x0012', '\x0013', '\x0014', '\x0015', 
'\x0016', '\x0017', '\x0018', '\x0019', '\x001a', '\x001b', '\x001c', '\x001d', 
'\x001e', '\x001f', 
':', '*', '?', '\\', '/'

Note that, in addition, there are reserved names such as prn, con, com1, com2,... , lpt1, lpt2,...
