       The _<_f_m_t_m_s_g_._h_> header shall define the following symbolic constants:

       MM_HARD       Source of the condition is hardware.

       MM_SOFT       Source of the condition is software.

       MM_FIRM       Source of the condition is firmware.

       MM_APPL       Condition detected by application.

       MM_UTIL       Condition detected by utility.

       MM_OPSYS      Condition detected by operating system.

       MM_RECOVER    Recoverable error.

       MM_NRECOV     Non-recoverable error.

       MM_HALT       Error causing application to halt.

       MM_ERROR      Application has encountered a non-fatal fault.

       MM_WARNING    Application has detected unusual non-error condition.

       MM_INFO       Informative message.

       MM_NOSEV      No severity level provided for the message.

       MM_PRINT      Display message on standard error.

       MM_CONSOLE    Display message on system console.

       The table below indicates the null values and identifiers for _f_m_t_m_s_g()
       arguments. The _<_f_m_t_m_s_g_._h_> header shall define the symbolic constants in
       the IIddeennttiiffiieerr column, which shall have the type indicated in the TTyyppee
       column:

                    +---------+--------+------------+------------+
       The _<_f_m_t_m_s_g_._h_> header shall also define the following symbolic
       constants for use as return values for _f_m_t_m_s_g():

       MM_OK         The function succeeded.

       MM_NOTOK      The function failed completely.

       MM_NOMSG      The function was unable to generate a message on standard
                     error, but otherwise succeeded.

       MM_NOCON      The function was unable to generate a console message,
                     but otherwise succeeded.

       The following shall be declared as a function and may also be defined
       as a macro. A function prototype shall be provided.


           int fmtmsg(long, const char *, int,
               const char *, const char *, const char *);
