NAME
dwarf_add_fde_inst - add a call frame instruction to a DWARF frame
descriptor
LIBRARY
DWARF Access Library (libdwarf, -ldwarf)
SYNOPSIS
#include <libdwarf.h>
Dwarf_P_Fde
dwarf_add_fde_inst(Dwarf_P_Fde fde, Dwarf_Small op, Dwarf_Unsigned val1,
Dwarf_Unsigned val2, Dwarf_Error *err);
DESCRIPTION
Function dwarf_add_fde_inst() adds a call frame instruction to the DWARF
frame descriptor referenced by argument fde.
Argument fde should reference a frame descriptor allocated using
dwarf_new_fde(3).
Argument op specifies the operator for the frame instruction. The DWARF
standard defines the set of legal values for this argument.
Argument val1 specifies the first operand of the frame instruction.
Argument val2 specifies the second operand of the frame instruction.
If argument err is not NULL, it will be used to store error information
in case of an error.
RETURN VALUES
On success, function dwarf_add_fde_inst() returns the frame descriptor
given in argument fde. In case of an error, function
dwarf_add_fde_inst() returns DW_DLV_BADADDR and sets the argument err.
ERRORS
Function dwarf_add_fde_inst() can fail with:
[DW_DLE_ARGUMENT] Argument fde was NULL.
[DW_DLE_FRAME_INSTR_EXEC_ERROR] The frame instruction operator
specified in argument op was invalid.
[DW_DLE_MEMORY] An out of memory condition was
encountered during the execution of the
function.
