     1This document serves as an overview of HelenOS standard user space API implemented in ''HelenOS C library'' and the relation of this API to common standards such as "C Standard Library" (as defined by various ISO C standards, such as C99) and ''C POSIX Library'' standards.

     3'''General note:''' The primary aim of ''HelenOS C library'' is not a to be 100% compatible with the standards. For both many fundamental reasons (HelenOS is not an unix-like operating system) and practical reasons (our subjective dislike of some aspects of the standards, security issues, etc.) the ''HelenOS C library'' follows the standards very loosely. Many functions are not implemented because lack of current need or simple because lack of manpower and many functions closely resemble their standard-compliant counterparts, but behave very slightly differently.
