setnetent()--Open Network Database

 #include <netdb.h>

 void setnetent(int stay_open)

The setnetent() function is used to prepare for sequential access to the network database file. setnetent() opens the file and repositions the file marker to the beginning of the file.

Parameters

stay_open

(Input) A value that indicates whether to leave the database file open after each getnetbyname() and getnetbyaddr(). A nonzero value will result in the database file being left open.

Authorities

No authorization is required.

Usage Notes

1. System i^® Navigator or the following CL commands can be used to access the network database file:
   
   
   • WRKNETTBLE (Work with Network Table Entries)
   • ADDNETTBLE (Add Network Table Entry)
   • RMVNETTBLE (Remove Network Table Entry)
   
   
2. Do not use the setnetent() function in a multithreaded environment. See the multithread alternative setnetent_r() function.
   
   
3. 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 setnetent() API is mapped to qso_setnetent98().
