		unsigned	applied
	)

GLboolean _mesa_layout_parameters

(

struct asm_parser_state *

state

)

XXX description???

Returns:

GL_TRUE for success, GL_FALSE for failure

static int copy_indirect_accessed_array	(	struct gl_program_parameter_list *	src,
		struct gl_program_parameter_list *	dst,
		unsigned	first,
		unsigned	count
	)			[static]

Copy indirect access array from one parameter list to another.

Parameters:

	src	Parameter array copied from
	dst	Parameter array copied to
	first	Index of first element in src to copy
	count	Number of elements to copy

Returns:

The location in dst of the first element copied from src on success. -1 on failure.

Warning:

This function assumes that there is already enough space available in dst to hold all of the elements that will be copied over.
