5 The GNU C Library interface

The functions described in this chapter are exported by the library (vicare glibc). The API attempts to create a one–to–one Scheme functions mapping towards GNU C Library functions, keeping the same semantics as much as possible; the platform’s own documentation is relevant at the Scheme level.

NOTE These bindings are included and installed by default and they can be excluded at compile time by giving the option --disable-glibc to the configure stript.

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.

On non–GNU C Library platforms we must avoid calling these functions, else the behaviour is undefined.

The availability of the GNU C Library API can be tested at run–time with the function vicare-built-with-glibc-enabled from (vicare) ((vicare-scheme)vicare-built-with-glibc-enabled), and at expand–time with the clause glibc-enabled of cond-expand from SRFI-0 (see glibc-enabled).
