kmp_i18n_id.inc defines kmp_i18n_id_t type. It is an enumeration with identifiers of all the

Low-level functions handling message catalog. __kmp_i18n_open() opens message catalog,
__kmp_i18n_closes() it. Explicit opening is not required: if message catalog is not yet open,
__kmp_i18n_catgets() will open it implicitly. However, catalog should be explicitly closed,
otherwise resources (mamory, handles) may leak.
__kmp_i18n_catgets() returns read-only string. It should not be freed.
KMP_I18N_STR macro simplifies acces to strings in message catalog a bit. Following two lines are
equivalent:
__kmp_i18n_catgets( kmp_i18n_str_Warning )
KMP_I18N_STR( Warning )

High-level interface for printing strings targeted to the user.
All the strings are divided into 3 types:
* messages,
* hints,
* system errors.
There are 3 kind of message severities:
* informational messages,
* warnings (non-fatal errors),
* fatal errors.
For example:
OMP: Warning #2: Cannot open message catalog "libguide.cat": (1)
OMP: System error #2: No such file or directory (2)
OMP: Hint: Please check NLSPATH environment variable. (3)
OMP: Info #3: Default messages will be used. (4)
where
(1) is a message of warning severity,
(2) is a system error caused the previous warning,
(3) is a hint for the user how to fix the problem,
(4) is a message of informational severity.
Usage in complex cases (message is accompanied with hints and system errors):
int error = errno; // We need save errno immediately, because it may be changed.
__kmp_msg(
kmp_ms_warning, // Severity
KMP_MSG( CantOpenMessageCatalog, name ), // Primary message
KMP_ERR( error ), // System error
KMP_HNT( CheckNLSPATH ), // Hint
__kmp_msg_null // Variadic argument list finisher
);
Usage in simple cases (just a message, no system errors or hints):
KMP_INFORM( WillUseDefaultMessages );
KMP_WARNING( CantOpenMessageCatalog, name );
KMP_FATAL( StackOverlap );
KMP_SYSFAIL( "pthread_create", status );
KMP_CHECK_SYSFAIL( "pthread_create", status );
KMP_CHECK_SYSFAIL_ERRNO( "gettimeofday", status );
