Low-level Unix wrapper types.
[Edit]
Remarks
The Mono.Unix.Native namespace contains
low-level wrapper classes, structures, and enumerations
which are accessible from the Mono.Unix.Native.Syscall
and Mono.Unix.Native.Stdlib classes, which are
a low-level wrappers over ANSI C, POSIX and Unix system calls and library
functions.
Note: Thread-safety wasn't handled in the original Unix API. While
some degree of thread-safety is provided from managed code, it is
impossible to provide full thread-safety for interactions between
managed and unmanaged code. For example, if you DllImport into a C
library which uses non-thread-safe Unix functions which are also
exposed in Mono.Unix.Native, you may have threading issues including, but not
limited to, memory corruption.
An effort is made to provide thread-safety from managed code,
but it is impossible to know all dependencies for all potential
Unix-like platforms. For example, is Mono.Unix.Native.Stdlib.fopen thread-safe? It appears to be under
glibc, but isn't necessarily under all Unix platforms.
Mono.Unix.Native.Stdlib assumes that it is. Only obviously
unsafe exports are actually synchronized from managed code, such as
Mono.Unix.Native.Stdlib.tmpnam and
Mono.Unix.Native.Stdlib.strerror.

Classes
| Type | Reason |
|---|
| CdeclFunction | Permits calling a varargs (cdecl) function from a library. |
| Dirent | Information about a directory entry. |
| FilePosition | A wrapper for the platform-specific fpos_t. |
| Fstab | File system descriptor file entry. |
| Group | Group database entry. |
| NativeConvert | Performs conversions between managed and unmanaged enumeration
values. |
| Passwd | Password database entry. |
| Stdlib | C Standard Library functions. |
| Syscall | The Syscall wrapper class makes it possible to execute the defined system calls. For more information on any of these system calls, the linux manual system (man) has exhaustive information on each syscall in section two: 'man 2 chdir' (or often chdir(2)) for example would give information related to chdir, including error codes, which are in general not listed here. |
| Utsname | Documentation for this section has not yet been entered. |
