NOF API Verbs (REGISTER_INDICATION_SINK to UNREGISTER_INDICATION_SINK)

SET_KERNEL_MEMORY_LIMIT

Chapter 51044

SET_KERNEL_MEMORY_LIMIT

This verb speciﬁes a limit on the amount of kernel memory that

SNAplus2 can use at any one time. This allows you to ensure that

memory is available for other processes on the HP-UX computer.

You can also specify the kernel memory limit when starting the

SNAplus2 software (for more information, see the HP-UX SNAplus2

Administration Guide). This verb overrides the limit, if any, speciﬁed

when starting the SNAplus2 software.

VCB Structure

typedef struct set_kernel_memory_limit

{

AP_UINT16 opcode; /* verb operation code */

unsigned char reserv2; /* reserved */

unsigned char format; /* reserved */

AP_UINT16 primary_rc; /* primary return code */

AP_UINT32 secondary_rc; /* secondary return code */

AP_UINT32 limit; /* kernel memory limit, 0 => no limit */

} SET_KERNEL_MEMORY_LIMIT;

Supplied Parameters

The application supplies the following parameters:

opcode

AP_SET_KERNEL_MEMORY_LIMIT

limit

The maximum amount of kernel memory that

SNAplus2 should use at any time, in bytes. If a

SNAplus2 component attempts to allocate kernel

memory that would take the total amount of memory

currently allocated to SNAplus2 components above this

limit, the allocation attempt will fail.

To remove the limit set by a previous

SET_KERNEL_MEMORY_LIMIT verb, specify zero.
