Syscalls are OS functions exposed by Ndless to C and assembly programs. This article describes the syscalls currently available with Ndless 1.7.

Your help is needed to make this list grow to a full-fledged library. Try to find new syscalls, test them and share them for integration in Ndless.

Functions marked with (*) are available only if the program is linked against Newlib, i.e. when the nspire-ld switch -nostdlib is not used.

C standard library
