'''$GET_ALIGN_FAULT_DATA'' ([[Alpha]] and [[Itanium|I64]]) is a [[System Service|system service]] that 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.
When buffered user alignment fault data reporting is enabled, the operating system writes each alignment fault into a user-defined buffer. The user must poll this buffer periodically to read the data.

The user must call the [[$START_ALIGN_FAULT_REPORT]] service to enable buffered user alignment fault data reporting. For more information about buffered user alignment fault data reporting, see the $START_ALIGN_FAULT_REPORT system service.

=Format=
<nowiki>SYS$GET_ALIGN_FAULT_DATA</nowiki> [[#buffer|buffer]]<nowiki> ,</nowiki>[[#buffer_size|buffer_size]]<nowiki> ,</nowiki>[[#return_size|return_size]]

C Prototype:
int sys$get_align_fault_data (void *buffer, int buffer_size, int *return_size);

=Arguments=
==buffer==
{{SyservArgument|address|longword (unsigned)|read/write|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==
{{SyservArgument|byte count|longword (signed)|read|by value}}

The size, in bytes, of the buffer specified by the buffer argument.

==return_size==
{{SyservArgument|longword_signed|longword (signed)|write|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.
