NAME top

   addseverity - introduce new severity classes

LIBRARY top

   Standard C library (_libc_, _-lc_)

SYNOPSIS top

   **#include <fmtmsg.h>**

   **int addseverity(int** _severity_**, const char ***_s_**);**

Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

   **addseverity**():
       Since glibc 2.19:
           _DEFAULT_SOURCE
       glibc 2.19 and earlier:
           _SVID_SOURCE

DESCRIPTION top

   This function allows the introduction of new severity classes
   which can be addressed by the _severity_ argument of the [fmtmsg(3)](../man3/fmtmsg.3.html)
   function.  By default, that function knows only 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 _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 nonnegative.

RETURN VALUE top

   Upon success, the value **MM_OK** is returned.  Upon error, the return
   value is **MM_NOTOK**.  Possible errors include: out of memory,
   attempt to remove a nonexistent or default severity class.
