endprotoent()--Close Protocol Database

 #include <netdb.h>

 void endprotoent()

The endprotoent() function is used to close the protocols database file. The file is opened by those functions that retrieve information about a protocol (for example, getprotoent()).

Authorities

No authorization is required.

Usage Notes

1. When the _XOPEN_SOURCE macro defined to the value 520 or greater, the protocols file is always closed. When the _XOPEN_SOURCE macro is not so defined, the protocols file is not closed if a setprotoent() with a nonzero parameter value was previously completed.
   
   
2. System i^® Navigator or the following CL commands can be used to access the protocol database file:
   • WRKPCLTBLE (Work with Protocol Table Entries)
     
     
   • ADDPCLTBLE (Add Protocol Table Entry)
     
     
   • RMVPCLTBLE (Remove Protocol Table Entry)
   
   
   
3. Do not use the endprotoent() function in a multithreaded environment. See the multithread alternative endprotoent_r() function.
   
   
4. When you develop in C-based languages and an application is compiled with the _XOPEN_SOURCE macro defined to the value 520 or greater, the endprotoent() API is mapped to qso_endprotoent98().
