dwarf_add_fde_inst

DWARF_ADD_FDE_INST(3)					   BSD Library Functions Manual 				     DWARF_ADD_FDE_INST(3)

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.
