setprotoent

Opens, rewinds, or closes the protocols database file.

#include  <netdb.h>

void setprotoent  (int stay_open);

stay_open

Specifies a value used to indicate when to close the protocols database file:

0 (zero) to close the host database file after each call to the getprotoent routine.
nonzero to keep the host database file open after each call.

The setprotoent routine opens, or rewinds the protocols database file and sets the file marker to the beginning of the file.

Passing a nonzero value to the stay_open parameter keeps the connection open until you call the endprotoent, or exit routine.

See also endprotoent, exit, and getprotoent in this section.

1	Indicates success.
0	Indicates an error; unable to open the protocols database file.
