Синопсис (Synopsis)

#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

Описание (Description)

This function allows the introduction of new severity classes
       which can be addressed by the severity argument of the fmtmsg(3)
       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.

Возвращаемое значение (Return value)

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.
