The POSIX functions are exported by the library (vicare
posix). The API attempts to create a one–to–one Scheme functions
mapping towards POSIX functions, keeping the same semantics as much
as possible; the platform's own documentation is relevant at the Scheme
level. posix not for a list of POSIX functions not interfaced
in this library, and reasons for not doing it.
To avoid name collisions with bindings exported by (ikarus) and
(vicare), when importing (vicare posix) it is mandatory
to assign it a prefix as follows:
(import (vicare)
(prefix (vicare posix) px.))
All the constants needed to use the interface are available as
identifier syntaxes exported by the (vicare platform constants)
library; if a constant value is not exported file a feature request for
the project. If a constant is not defined on a platform: its value is
set to #f.
The library (vicare platform features) exports one identifier
syntax for each HAVE_ symbol defined by Vicare
configure script, expanding to #t or #f.
