       nsg_set  - Set NUMA Scheduling Group owner and permissions
       (libnuma library)

SYNOPSIS    [Toc]    [Back]

       #include <numa.h>

       int nsg_set(
               nsgid_t nsg,
               nsgid_ds_t *attrib );

PARAMETERS    [Toc]    [Back]

       Specifies the NUMA Scheduling Group (NSG).   Points  to  a
       structure containing owner and permission attributes.

DESCRIPTION    [Toc]    [Back]

       The nsg_set() function sets the NSG owner IDs (user ID and
       group ID) and permissions (mode)  by  using  the  nsgid_ds
       structure pointed to by attrib.

RESTRICTIONS    [Toc]    [Back]

       The effective user ID of the calling process must be equal
       to the value of nsg_perm.cuid or nsg_perm.uid in the associated
  nsgid_ds  structure,  or  the calling process must
       have write permissions to the NSG.

RETURN VALUES    [Toc]    [Back]

       Success. In this case, nsg_set() set the NSG owner IDs and
       permissions as specified.  Failure. In this case, errno is
       set to indicate the error.

ERRORS    [Toc]    [Back]

       If the nsg_set() function fails, it sets errno to  one  of
       the  following  values  for  the  specified condition: The
       calling process  does  not  have  write  permission.   The
       attrib  argument  specifies  an  invalid address.  The nsg
       argument does not specify a valid NSG ID.
