processing at a later time. In some cases, verb processing is complete

when SNAplus2 returns control to the application, so SNAplus2 does not

use the application's callback routine.

Function Call

AP_UINT16 nof_async(

AP_UINT32 target_handle,

void * nofvcb,

NOF_CALLBACK (*comp_proc),

AP_CORR corr

);

typedef void (*NOF_CALLBACK) (

AP_UINT32 target_handle,

void * nofvcb,

AP_CORR corr

AP_UINT32 indic_length

);

typedef union ap_corr {

void * corr_p;

AP_UINT32 corr_l;

int corr_i;

} AP_CORR;

For more information about the parameters in the NOF_CALLBACK

structure, see “The Callback Routine Speciﬁed on the nof_async Entry

Point”.

Supplied Parameters

An application supplies the following parameters when it uses the

nof_async entry point:

target_handle

This parameter is supplied in one of the following

ways:

• For the following verbs, this parameter is not used;

set it to 0 (zero). If the verb completes successfully,

SNAplus2 returns the target handle as one of the

VCB parameters. The application then uses the

target handle for subsequent verbs.
