Detailed Description

Common Entry

Both the CIE and the FDE share the length field. The length field can have two different sizes, so this class provides a simple way to describe the CIE/FDE itself (entry start / end), the portion of the CIE/FDE that does not include the length field (the payload), as well as some other functions for convenience.

Next CIE/FDE

Moves to the next CIE/FDE in the list. If the CIE/FDE is invalid, this function does nothing. If is possible that this function could result in an invalid CIE/FDE, which can be used in a for loop to determine when the end of the list has been approached.

Returns

next CIE/FDE

Definition at line 150 of file eh_frame.cpp.

operator bool()

common_entry::operator bool ( ) const

inline

Valid

Returns

returns true if the CIE/FDE is valid

Definition at line 271 of file eh_frame.h.

is_cie()

bool common_entry::is_cie ( ) const

inline

Is CIE

Returns

returns true if this is a CIE

Definition at line 278 of file eh_frame.h.

is_fde()

bool common_entry::is_fde ( ) const

inline

Is FDE

Returns

returns true is this is an FDE

Definition at line 285 of file eh_frame.h.

entry_start()

char* common_entry::entry_start ( ) const

inline

Entry Start

Returns

returns the start of the CIE/FDE in memory

Definition at line 292 of file eh_frame.h.

entry_end()

char* common_entry::entry_end ( ) const

inline

Entry End

Returns

returns the end of the CIE/FDE in memory

Definition at line 299 of file eh_frame.h.

payload_start()

char* common_entry::payload_start ( ) const

inline

Payload Start

Returns

returns the start of the CIE/FDE's payload in memory, which is the portion of the CIE/FDE that does not contain the length field

Definition at line 307 of file eh_frame.h.

payload_end()

char* common_entry::payload_end ( ) const

inline

Payload End

Returns

returns the end of the CIE/FDE's payload in memory, which is the portion of the CIE/FDE that does not contain the length field. Note that this should be the same as entry_end

Definition at line 316 of file eh_frame.h.

eh_frame()

eh_frame_t common_entry::eh_frame ( ) const

inline

EH Framework

Returns

returns the .eh_frame associated with this CIE/FDE

Definition at line 323 of file eh_frame.h.

parse()

virtual void common_entry::parse ( char *  addr )

protectedpure virtual

Implemented in fd_entry, and ci_entry.

non_virtual_parse()

void common_entry::non_virtual_parse ( char *  addr )
