NAME    [Toc]    [Back]

       suser  -  General:  Checks whether the current user is the
       superuser

SYNOPSIS    [Toc]    [Back]

       #include <sys/proc.h> #include <sys/acct.h>

       int suser(
               struct u_cred *cred,
               struct flag_field *ac_flag );

ARGUMENTS    [Toc]    [Back]

       Specifies a pointer to the  credentials  for  the  current
       process.   Specifies  a  pointer to a flag_field structure
       that contains accounting flags.

DESCRIPTION    [Toc]    [Back]

       The suser routine checks whether the current user  is  the
       superuser.  If the test succeeds and ac_flag is not a null
       pointer, the ASU flag is set in the  flag_field  structure
       pointed  to  by ac_flag. The most common value for ac_flag
       is as follows:

       &u.u_acflag

NOTES    [Toc]    [Back]

       You use the suser routine only if the security feature  is
       not  enabled.  If the security feature is enabled, use the
       privileged routine to determine if the current process has
       the appropriate privilege.

RETURN VALUES    [Toc]    [Back]

       If  the  current  user is the superuser, the suser routine
       returns the value  0  (zero).  Otherwise,  it  returns  an
       error.

ERRORS    [Toc]    [Back]

       The current user is not the superuser.
