SYNOPSIS
#include <arraysvcs.h>
extern aserror_t aserrorcode;
#define aserrnoc(errorcode)
#define aserrwhatc(errorcode)
#define aserrwhyc(errorcode)
#define aserrextrac(errorcode)
#define aserrno ...
#define aserrwhat ...
#define aserrwhy ...
#define aserrextra ...
DESCRIPTIONaserrorcode is a global variable maintained by the array services
library, libarray. Many array services functions store detailed status
in this variable when they complete. The variable aserrorcode is made up
of four fields, which can be accessed with the following macros:
aserrno
Summarizes the results of the most recent array services function.
This is similar to the libc variable errno in that it is only set if
some sort of error condition occurred.
aserrwhat
For certain values of aserrno, this field describes the particular
component that experienced trouble.
aserrwhy
For certain values of aserrno, this field describes why the error
occurred.
aserrextra
Certain combinations of aserrno, aserrwhat and/or aserrwhy may cause
some additional information to be stored in this field. The exact
information depends on the particular combination.
The specific values that can be stored in these fields are described in
the file <arraysvcs.h>.
The individual fields of an error code can be extracted from an arbitrary
value using the aserrnoc, aserrwhatc, aserrwhyc and aserrextrac functions
respectively.
