|

|
|---|
| 19 | * XXX := functional group
|
|---|
| 20 | * YYY := stdlib/OS function name
|
|---|
| 21 | *
|
|---|
| 22 | * Continuing with the theme of PerlIO, all OS functionality was
|
|---|
| 23 | * encapsulated into one of several interfaces.
|
|---|
| 24 | *
|
|---|
| 25 | * PerlIO - stdio
|
|---|
| 26 | * PerlLIO - low level I/O
|
|---|
| 27 | * PerlMem - malloc, realloc, free
|
|---|
| 28 | * PerlDir - directory related
|
|---|
| 29 | * PerlEnv - process environment handling
|
|---|
| 30 | * PerlProc - process control
|
|---|
| 31 | * PerlSock - socket functions
|
|---|
| 32 | *
|
|---|
| 33 | *
|
|---|
| 34 | * The features of this are:
|
|---|
| 35 | * 1. All OS dependant code is in the Perl Host and not the Perl Core.
|
|---|
| 36 | * (At least this is the holy grail goal of this work)
|
|---|
| 37 | * 2. The Perl Host (see perl.h for description) can provide a new and
|
|---|
| 38 | * improved interface to OS functionality if required.
|
|---|
| 39 | * 3. Developers can easily hook into the OS calls for instrumentation
|
|---|
| 40 | * or diagnostic purposes.
|
|---|
| 41 | *
|
|---|
| 42 | * What was changed to do this:
|
|---|
| 43 | * 1. All calls to OS functions were replaced with PerlXXX_YYY
|
|---|
| 44 | *
