NAMEaddseverity - introduce new severity classes
int addseverity(int severity , const char * s );
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
DESCRIPTIONThis function allows the introduction of new severity classes which can be addressed by the severity argument 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 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 VALUEUpon 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.
VERSIONSaddseverity() is provided in glibc since version 2.1.
CONFORMING TOThis function is not specified in the X/Open Portability Guide although the fmtmsg(3) function is. It is available on System V systems.
NOTESNew severity classes can also be added by setting the environment variable SEV_LEVEL.
