addseverity(3) Library Functions Manual addseverity(3)
addseverity - introduce new severity classes
Standard C library (libc, -lc)
#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
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.
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.
For an explanation of the terms used in this section, see
attributes(7).
