OSS Library Calls Reference Manual

TNS/E code that runs on H-series systems. Discussions of TNS or accelerated code

behavior in the OSS environment apply only to G-series systems; H-series systems do

not support TNS or accelerated code execution in the OSS environment.

Audience

This manual is for system and application programmers who want to use the OSS

application program interface provided with the HP NonStop operating system. The

manual assumes that the reader is a programmer and is familiar with the C programming

language.

Purpose

This manual provides a complete reference to all OSS system function calls and their

related ﬁles and miscellaneous topics.

Document Usage

This manual contains a portion of the online manual reference (man) pages. These

reference pages are arbitrarily divided into sections for ease of access.

Reference Page Format

The reference pages for functions, ﬁles, and miscellaneous topics in this manual use the

following format. If a heading has no contents for a particular reference page, it is

omitted.

NAME Function, ﬁle, or miscellaneous topic name and purpose.

LIBRARY Library containing the function. The library is identiﬁed in terms of the |

run-time environment in which the compiled application must run. For |

example, an "H-series native Guardian process" must use the speciﬁed |

library when the c89 -Wtarget=TNS/E and -Wsystype=guardian ﬂags |

are speciﬁed or used by default.

SYNOPSIS Appropriate syntax, including header ﬁles to be included and all

parameter types. Some header ﬁles are required for POSIX.1-compliant

applications but are optional for applications conforming to other

standards. These header ﬁles are noted as "optional except for

POSIX.1."
