stkarg_area_info_t Struct Reference

Detailed Description

Some calling conventions foresee special areas on the stack for call arguments.

This structure lists their sizes.

Public Attributes
size_t	cb = sizeof(stkarg_area_info_t)
sval_t	stkarg_offset = 0
	Offset from the SP to the first stack argument (can include linkage area) examples: pc: 0, hppa: -0x34, ppc aix: 0x18.
sval_t	shadow_size = 0
	Size of the shadow area. More...
sval_t	linkage_area = 0
	Size of the linkage area. More...
