| llvm/lib/Support/Unix README |
| =========================== |
| |
| This directory provides implementations of the lib/System classes that |
| are common to two or more variants of UNIX. For example, the directory |
| structure underneath this directory could look like this: |
| |
| Unix - only code that is truly generic to all UNIX platforms |
| Posix - code that is specific to Posix variants of UNIX |
| SUS - code that is specific to the Single Unix Specification |
| SysV - code that is specific to System V variants of UNIX |
| |
| As a rule, only those directories actually needing to be created should be |
| created. Also, further subdirectories could be created to reflect versions of |
| the various standards. For example, under SUS there could be v1, v2, and v3 |
| subdirectories to reflect the three major versions of SUS. |
