All symbols are in the SB-POSIX
package. This package contains a
Lisp function for each supported Unix system call or function, a
variable or constant for each supported Unix constant, an object type
for each supported Unix structure type, and a slot name for each
supported Unix structure member. A symbol name is derived from the C
binding's name, by (a) uppercasing, then (b) removing leading
underscores (#\_
) then replacing remaining underscore characters
with the hyphen (#\-
). The requirement to uppercase is so that in
a standard upcasing reader the user may write sb-posix:creat
instead of sb-posix:|creat|
as would otherise be required.
No other changes to “Lispify” symbol names are made, so creat()
becomes CREAT
, not CREATE
.
The user is encouraged not to (USE-PACKAGE :SB-POSIX)
but instead
to use the SB-POSIX:
prefix on all references, as some of the
symbols symbols contained in the SB-POSIX package have the same name as
CL symbols (OPEN
, CLOSE
, SIGNAL
etc).
