Member Function Documentation

GetAddress()

unsigned DebugStackwalk::Signature::GetAddress

(

int

n

)

const

Get a single address from the signature.

The address at index 0 is always on top of the stack.

Parameters

n	index, 0..Size()-1

Returns

signature address

Definition at line 133 of file debug_stack.cpp.

GetSymbol() [1/2]

void DebugStackwalk::Signature::GetSymbol ( unsigned addr, char * buf, unsigned bufSize )

static

Determines symbol for given address.

The data is returned in the form <addr> <module>+NN, <sym>+NN, <file>:<line>+NN

Parameters

addr	function address
buf	return buffer
bufSize	size of return buffer, minimum is 64 bytes (256 recommended)

Definition at line 139 of file debug_stack.cpp.

GetSymbol() [2/2]

void DebugStackwalk::Signature::GetSymbol ( unsigned addr, char * bufMod, unsigned sizeMod, unsigned * relMod, char * bufSym, unsigned sizeSym, unsigned * relSym, char * bufFile, unsigned sizeFile, unsigned * line, unsigned * relLine )

static

Determines symbol for given address.

Parameters

addr	function address
bufMod	module buffer, may be NULL
sizeMod	size of buffer, including NUL, minimum 16 if given
relMod	relative address within module, may be NULL
bufSym	symbol buffer, may be NULL
sizeSym	size of buffer, including NUL
relSym	relative address within symbol, may be NULL
bufFile	file name buffer, may be NULL
sizeFile	size of buffer, including NUL
line	line number, may be NULL
relLine	relative address within line, may be NULL

Definition at line 204 of file debug_stack.cpp.

operator<()

bool DebugStackwalk::Signature::operator< ( const Signature & other ) const

inline

Strong ordering operator.

Signatures are ordered by looking at the bottom of the stack first. Implemented inline so that STL algorithms using this operator can be compiled more efficiently.

Definition at line 93 of file debug_stack.h.

operator=()

DebugStackwalk::Signature & DebugStackwalk::Signature::operator=

(

const Signature &

src

)

Definition at line 123 of file debug_stack.cpp.

Size()

unsigned DebugStackwalk::Signature::Size ( void ) const

inline

Determine the number of addresses in this signature.

Returns

number of addresses in this signature

Definition at line 74 of file debug_stack.h.
