NAME
     dwarf_start_macro_file -- mark the start of a source file inclusion

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS
     #include <libdwarf.h>

     int
     dwarf_start_macro_file(Dwarf_P_Debug dbg, Dwarf_Unsigned lineno,
         Dwarf_Unsigned fileindex, Dwarf_Error *err);

DESCRIPTION
     Function dwarf_start_macro_file() marks the start of a new source file
     inclusion.

     Argument dbg should reference a DWARF producer instance allocated using
     dwarf_producer_init(3) or dwarf_producer_init_b(3).

     Argument lineno specifies the line number of the source line where the
     source file inclusion occurs.  A value of zero is used to indicate the
     file for the compilation unit source itself.

     Argument fileindex specifies the index of the source file that is being
     included.  Valid source file indices are those returned by
     dwarf_add_file_decl(3).

     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_start_macro_file() returns DW_DLV_OK.  In case
     of an error, function dwarf_start_macro_file() returns DW_DLV_ERROR and
     sets the argument err.

ERRORS
     Function dwarf_start_macro_file() can fail with:

     [DW_DLE_ARGUMENT]       Argument dbg was NULL.

     [DW_DLE_MEMORY]         An out of memory condition was encountered during
                             the execution of the function.
