get password file entry

SYNOPSIS

    #include <pwd.h>
    #include <sys/types.h>
      struct passwd *getpwnam(const char *  name );  
      struct passwd *getpwuid(uid_t  uid );  
    

DESCRIPTION

    The getpwnam() function returns a pointer to a structure containing the broken out fields of a line from /etc/passwd for the entry that matches the user name name.

    The getpwuid() function returns a pointer to a structure containing the broken out fields of a line from /etc/passwd for the entry that matches the user uid uid.

    The passwd structure is defined in <pwd.h> as follows:

      8n 16n 32n
      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 */
      };
