and later H-series RVUs also applies to systems running J06.03 and later J-series RVUs.

Audience

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

provided with the 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 library function calls and their

related ﬁles and miscellaneous topics.

Document Usage

This manual contains a portion of the online 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."
