How to create files with specific security permissions in Linux? (i.e. the equivalent of Win32 CreateFile+SECURITY_ATTRIBUTES)

Vote count:

With Windows' Win32 API it's possible to create files and assign to them proper security permissions (e.g. some users can read from and write to the file, other users in another group can only read but not write, etc.), using CreateFile() and it's SECURITY_ATTRIBUTES parameter.

Does Linux offer something similar? Which functions and data structures should be used for that purpose?

(I can be missing something, but the classical C fopen does not seem to offer a similar security permission setting feature...)
