Struct idalib_sys::xref::xrefblk_t

#[repr(C)]
pub struct xrefblk_t {
    pub from: ea_t,
    pub to: ea_t,
    pub iscode: u8,
    pub type_: u8,
    pub user: u8,
}

Structure to enumerate all xrefs. This structure provides a way to access cross-references from a given address. For example:

\code xrefblk_t xb; for ( bool ok=xb.first_from(ea, XREF_ALL); ok; ok=xb.next_from() ) { // xb.to - contains the referenced address } \endcode or: \code xrefblk_t xb; for ( bool ok=xb.first_to(ea, XREF_ALL); ok; ok=xb.next_to() ) { // xb.from - contains the referencing address } \endcode

First, all code references will be returned, then all data references. If you need only code references, stop calling next() as soon as you get a dref.

If you need only data references, pass #XREF_DATA flag to first(). You may not modify the contents of a xrefblk_t structure! It is read only.

Fields

from: ea_t

< the referencing address - filled by first_to(),next_to()

to: ea_t

< the referenced address - filled by first_from(), next_from()

iscode: u8

< 1-is code reference; 0-is data reference

type_: u8

< type of the last returned reference (::cref_t & ::dref_t)

user: u8

< 1-is user defined xref, 0-defined by ida

Implementations

impl xrefblk_t

pub unsafe fn new() -> impl New<Output = Self>

impl xrefblk_t

pub unsafe fn first_from( self: Pin<&mut Self>, _from: c_ulonglong, flags: c_int, ) -> bool

Get first xref from the given address (store in #to)

impl xrefblk_t

pub unsafe fn first_to( self: Pin<&mut Self>, _to: c_ulonglong, flags: c_int, ) -> bool
