struct typedef names that clash with stdlib

I have an issue where one of my struct typedefs, mode_t, clashes with one in the stdlib

mode_t is already defined in sys/types.h

whats best practice in this instance? to rename my struct to something else or is there some other way to resolve the clash?

If your program names clash with the library variable names, change the names in your program.

If the name conflicts in C program, then you need to rename your structure. In C++, you can use namespace.

Or if you want to use this name, then do not include sys/types.h.

Never have your own structure name or variable name that ends in _t. Regard all such names as reserved by either the compiler or the standard library.

Although technically legal by the C standard, many platforms (e.g. POSIX) explicitly forbid it.

Your best option is to rename your structure.
