Cross-Reference types

Describe categories of code/data xrefs. More...

Topics
	Cross-Reference type flags
	These flags are combined with a cref_t or dref_t value to describe the type of a cross reference.

Enumerations
enum	cref_t {   fl_U , fl_CF = 16 , fl_CN , fl_JF ,   fl_JN , fl_USobsolete , fl_F }
	CODE xref types. More...
enum	dref_t {   dr_U , dr_O , dr_W , dr_R ,   dr_T , dr_I , dr_S }
	DATA xref types. More...

Functions
idaman char ida_export	xrefchar (char xrtype)
	Get character describing the xref type.

Detailed Description

Describe categories of code/data xrefs.

Note

IDA handles the xrefs automatically and may delete an xref added by the user if it does not contain the #XREF_USER bit.

Enumeration Type Documentation

cref_t

enum cref_t

CODE xref types.

Enumerator
fl_U	unknown – for compatibility with old versions. Should not be used anymore.
fl_CF	Call Far This xref creates a function at the referenced location.
fl_CN	Call Near This xref creates a function at the referenced location.
fl_JF	Jump Far.
fl_JN	Jump Near.
fl_USobsolete	User specified (obsolete)
fl_F	Ordinary flow: used to specify execution flow to the next instruction.

dref_t

enum dref_t

DATA xref types.

Enumerator
dr_U	Unknown – for compatibility with old versions. Should not be used anymore.
dr_O	Offset The reference uses 'offset' of data rather than its value OR The reference appeared because the "OFFSET" flag of instruction is set. The meaning of this type is IDP dependent.
dr_W	Write access.
dr_R	Read access.
dr_T	Text (for forced operands only) Name of data is used in manual operand.
dr_I	Informational (a derived java class references its base class informationally)
dr_S	Reference to enum member (symbolic constant)
