suser(9r)
NAME
  suser - General: Checks whether the current user is the superuser

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

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

ARGUMENTS
  cred
      Specifies a pointer to the credentials for the current process.

  ac_flag
      Specifies a pointer to a flag_field structure that contains accounting
      flags.

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

ERRORS
  EPERM
      The current user is not the superuser.
