Function Documentation

bft_backtrace_address()

const char* bft_backtrace_address	(	bft_backtrace_t *	bt,
		int	depth
	)

Return address associated with a backtrace at a given depth.

Parameters

[in]	bt	pointer to backtrace description structure.
[in]	depth	index in backtrace structure (< bft_backtrace_size(bt)).

Returns

address at the given depth, or NULL.

bft_backtrace_create()

bft_backtrace_t* bft_backtrace_create

(

void

)

Build a backtrace description structure.

Returns

pointer to bft_backtrace_t backtrace descriptor (NULL in case of error, or if backtracing is unavailable on this architecture).

bft_backtrace_demangle()

void bft_backtrace_demangle

(

bft_backtrace_t *

bt

)

Demangle a backtrace description structure (for C++).

Parameters

[in,out]

bt

pointer to backtrace description structure.

bft_backtrace_destroy()

(

bft_backtrace_t *

bt

)

Free a backtrace description structure.

Parameters

[in,out]

bt

pointer to backtrace description structure.

Returns

NULL pointer.

bft_backtrace_file()

const char* bft_backtrace_file	(	bft_backtrace_t *	bt,
		int	depth
	)

Return file name associated with a backtrace at a given depth.

Parameters

[in]	bt	pointer to backtrace description structure.
[in]	depth	index in backtrace structure (< bft_backtrace_size(bt)).

Returns

file name at the given depth, or NULL.

bft_backtrace_function()

const char* bft_backtrace_function	(	bft_backtrace_t *	bt,
		int	depth
	)

Return function name associated with a backtrace at a given depth.

Parameters

[in]	bt	pointer to backtrace description structure.
[in]	depth	index in backtrace structure (< bft_backtrace_size(bt)).

Returns

function name at the given depth, or NULL.

bft_backtrace_print()

void bft_backtrace_print

(

int

start_depth

)

Print a backtrace.

Parameters

[in]

bft_backtrace_print_get()

bft_backtrace_print_t* bft_backtrace_print_get

(

void

)

Returns backtrace print function.

Returns

pointer to the backtrace print function.

fct

)

Sets a backtrace print function.

Parameters

[in]

fct

pointer to a bft_backtrace_print_t type function.

bft_backtrace_size()

int bft_backtrace_size

(

const bft_backtrace_t *

bt

)

Return the depth of a backtrace.

Parameters

[in]

bt

pointer to backtrace description structure.

Returns

backtrace depth.
