The first time it is called it returns the first entry; thereafter, it returns successive entries. The setpwent() function rewinds the file pointer to the beginning of the /etc/passwd file. The endpwent() function closes the /etc/passwd file. The passwd structure is defined in <pwd.h> as follows: struct passwd { char *pw_name; /* user name */ char *pw_passwd; /* user password */ uid_t pw_uid; /* user id */ gid_t pw_gid; /* group id */ char *pw_gecos; /* real name */ char *pw_dir; /* home directory */ char *pw_shell; /* shell program */ }; <h3>RETURN VALUE </h3> The getpwent() function returns the passwd structure, or NULL if there are no more entries or an error occurs. <h3>ERRORS </h3> ENOMEM Insufficient memory to allocate passwd structure. <h3>FILES </h3> /etc/passwdpassword database file <h3>CONFORMING TO </h3> SVID 3, BSD 4.3 </pre> <hr> <h3>SEE ALSO </h3><p> <a href=fgetpwent.htm>fgetpwent</a>, <a href=getpwnam.htm>getpwnam</a>, <a href=getpwnam.htm>getpwuid</a>, <a href=getpw.htm>getpw</a>, <pre> <h3>GNU April 9, 1993 1 </h3> </pre> <P> <hr> <p> <center> <table border=2 width=80%> <tr align=center> <td width=25%> <a href=../index.htm>Top</a> </td><td width=25%> <a href=../master_index.html>Master Index</a> </td><td width=25%> <a href=../SYNTAX/keywords.html>Keywords</a> </td><td width=25%> <a href=../FUNCTIONS/index.htm>Functions</a> </td> </tr> </table> </center> <p> <hr> This manual page was brought to you by <i>mjl_man V-2.0</i>
