setprotoent_r(3) [osf1 man page]
setprotoent(3) Library Functions Manual setprotoent(3) NAME
setprotoent, setprotoent_r - Open or rewind the protocols file LIBRARY
Standard C Library (libc.so, libc.a) SYNOPSIS
#include <netdb.h> void setprotoent( int stay_open); [Tru64 UNIX] The following function is supported in order to maintain backward compatibility with previous versions of the operating sys- tem. int setprotoent_r( int stay_open, struct protoent_data *proto_data); The following definition of the setprotoent() function does not conform to current standards and is supported only for backward compatibil- ity (see standards(5)): int setprotoent( int stay_open); STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: setprotoent(): XNS4.0 Refer to the standards(5) reference page for more information about industry standards and associated tags. PARAMETERS
Indicates when to close the protocols file. Specifying a value of 0 (zero) causes the file to be closed after each call to the setpro- toent() function. Specifying a nonzero value allows the protocols file to remain open after each function. [Tru64 UNIX] For setpro- toent_r() only, this points at a structure where setprotoent_r() stores information about the protocols file. DESCRIPTION
The setprotoent() (set protocol entry) function opens either the local /etc/protocols file or the NIS distributed protocols file and sets the file marker to the beginning of the file. To determine which file or files to search, and in which order, the system uses the switches in the /etc/svc.conf file. NOTES
[Tru64 UNIX] The setprotoent_r() function is the reentrant version of the setprotoent() function. It is supported in order to maintain backward compatibility with previous versions of the operating system. Upon successful completion, the setprotoent_r() function returns a value of 0 (zero). Otherwise, it returns a value of -1. [Tru64 UNIX] Note that before calling the setprotoent_r() function for the first time, you must zero-fill the protoent_data structure. The netdb.h header file defines the protoent_data structure. RETURN VALUES
[Tru64 UNIX] Upon successful completion, the version of setprotoent() provided for backward compatibility returns a value of 1. Other- wise, it returns a value of 0 (zero). ERRORS
Current industry standards do not define error values for the setprotoent() function. [Tru64 UNIX] If any of the following conditions occurs, the setprotoent_r() function sets errno to the corresponding value: The proto_data parameter is invalid. In addition, the setprotoent(), backward compatible version of setprotoent(), and setprotoent_r() functions can fail to open the file. In this case, errno will be set to the failure. FILES
Contains the protocol names. The database service selection configuration file. RELATED INFORMATION
Functions: endprotoent(3), getprotobyname(3), getprotobynumber(3), getprotoent(3). Files: protocols(4), svc.conf(4). Networks: nis_intro(7). Standards: standards(5). delim off setprotoent(3)
