NAME
addseverity - introduce new severity classes
SYNOPSIS
#define _SVID_SOURCE
#include <fmtmsg.h>
I int addseverity(int severity , const char * s );
DESCRIPTION
This function allows the introduction of new severity classes
which can be addressed by the
severity
parameter of the
fmtmsg(3)
function.
By default that latter function only knows how to
print messages for severity 0-4 (with strings (none), HALT,
ERROR, WARNING, INFO).
This call attaches the given string
s
to the given value
R severity .
If
s
is NULL, the severity class with the numeric value
severity
is removed.
It is not possible to overwrite or remove one of the default
severity classes.
The severity value must be non-negative.
RETURN VALUE
Upon success, the value
MM_OK
is returned.
Upon error, the return value is
R MM_NOTOK .
Possible errors include: out of memory, attempt to remove a
nonexistent or default severity class.
CONFORMING TO
This function is not specified in the X/Open Portability Guide
although the
fmtmsg(3)
function is.
It is available on System V
systems.
NOTES
New severity classes can also be added by setting the environment variable
R SEV_LEVEL .
