@chapter Process Dump Control Manager
@section Introduction
The process dump control manager provides a portable
interface for changing the path to which a process dump
is written. The capabilities in this manager were defined in
the POSIX 1003.1h/D3 proposed standard titled @b{Services for Reliable,
Available, and Serviceable Systems}.
The directives provided by the process dump control manager are:
@itemize @bullet
@item @code{dump_setpath} - Dump File Control
@end itemize
@section Background
There is currently no text in this section.
@section Operations
There is currently no text in this section.
@section Directives
This section details the process dump control manager's directives.
A subsection is dedicated to each of this manager's directives
and describes the calling sequence, related constants, usage,
and status codes.
@page
@subsection dump_setpath - Dump File Control
@subheading CALLING SEQUENCE:
@ifset is-C
@example
#include <dump.h>
int dump_setpath(
const char *path
);
@end example
@end ifset
@ifset is-Ada
@end ifset
@subheading STATUS CODES:
@table @b
@item EACESS
Search permission is denied for a component of the path prefix,
or write permission is denied on the directory containing the
file.
@item ENAMETOOLONG
The length of the argument exceeds @code{PATH_MAX} or a pathname
component is longer than @code{NAME_MAX} while @code{_POSIX_NO_TRUNC}
is in effect.
@item ENOENT
The path argument points to an empty string.
@item ENOTDIR
A component of the path prefix is not a directory.
@item EROFS
The directory entry specified resides on a read-only file system.
@end table
@subheading DESCRIPTION:
The @code{dump_setpath()} function defines the pathname where process
dumps are written. The pathname pointed to by @code{path} defines
where a process dump file is written if the calling process
terminates with a dump file. The @code{path} argument does not
name a directory.
If the @code{path} argument is NULL, the system does not write a
process dump file if the calling process terminates with a dump
file. If the @code{dump_setpath} function fails, the pathname for
writing process dumps does not change.
@subheading NOTES:
The @code{_POSIX_DUMP} feature flag is defined to indicate
this service is available.
