System Services, $GET ALIGN FAULT DATA (Alpha Only)

On Alpha systems, obtains data from the user image alignment
fault buffer if buffered user alignment fault data reporting has
been enabled.
This service accepts 64-bit addresses.
Format
SYS$GET_ALIGN_FAULT_DATA buffer ,buffer_size ,return_size
C Prototype
int sys$get_align_fault_data (void *buffer, int buffer_size,
int *return_size);
buffer
OpenVMS usage:address
type: longword (unsigned)
access: read/write
mechanism: by 32- or 64-bit reference
The user buffer in which the alignment fault data is to be
stored. The buffer is the 32- or 64-bit address of this user
buffer.
buffer_size
OpenVMS usage:byte count
type: longword (signed)
access: read
mechanism: by value
The size, in bytes, of the buffer specified by the buffer
argument.
return_size
OpenVMS usage:longword_signed
type: longword (signed)
access: write
mechanism: by 32- or 64-bit reference
The amount of data, in bytes, stored in the buffer. The return_
size argument is the 32- or 64-bit address of a naturally aligned
longword into which the service returns the size of the buffer.
The return_size is set to 0 if there is no data in the buffer.
