DWARF_ADD_FDE_INST(3)      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.
