POSIX Extensions

The extensions to the standard POSIX APIs can be divided into two groups:

• Restricted microkernel calls

• POSIX-like extended services

The restricted microkernel calls are directly available from the libc.a or libc.so libraries and include the following APIs:

• MIPC

• IPC

• LAP

To add POSIX-like extended services, you must specify the required library in your Imakefile. These services include the following APIs:

• Blackbox

• SysEvent

• LDAP
