DWARF_GET_RELOCATION_INFO_COUNT(3)			   BSD Library Functions Manual 			DWARF_GET_RELOCATION_INFO_COUNT(3)

NAME

     dwarf_get_relocation_info_count -- return the number of relocation arrays

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     int
     dwarf_get_relocation_info_count(Dwarf_P_Debug dbg, Dwarf_Unsigned *reloc_cnt, int *drd_buffer_version, Dwarf_Error *err);

DESCRIPTION

     Function dwarf_get_relocation_info_count() retrieves the total number of relocation arrays generated by a prior call to
     dwarf_transform_to_disk_form(3).

     Argument dbg should reference a DWARF producer instance allocated using dwarf_producer_init(3) or dwarf_producer_init_b(3).  The
     DW_DLC_SYMBOLIC_RELOCATIONS flag should have been set on the producer instance.

     Argument reloc_cnt should point to a location which will be set to the total number of relocation arrays generated.

     Argument drd_buffer_version should point to a location which will be set to the version number of the relocation structures returned (see the
     symbol DWARF_DRD_BUFFER_VERSION, defined in the header file <libdwarf.h>).

     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_get_relocation_info_count() returns DW_DLV_OK.	It returns DW_DLV_NO_ENTRY if the DW_DLC_SYMBOLIC_RELOCATIONS flag
     is not set on the producer instance.  In case of an error, function dwarf_get_relocation_info_count() returns DW_DLV_ERROR and sets the argu-
     ment err.

ERRORS

     Function dwarf_get_relocation_info_count() can fail with:

     [DW_DLE_ARGUMENT]	One of the arguments dbg, reloc_cnt or drd_buffer_version was NULL.

     [DW_DLE_NO_ENTRY]	The DW_DLC_SYMBOLIC_RELOCATIONS flag was not set.

DWARF_DEF_MACRO(3)					   BSD Library Functions Manual 					DWARF_DEF_MACRO(3)

NAME

     dwarf_def_macro -- add a macro definition to a DWARF producer instance

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     int
     dwarf_def_macro(Dwarf_P_Debug dbg, Dwarf_Unsigned lineno, char *name, char *value, Dwarf_Error *err);

DESCRIPTION

     Function dwarf_def_macro() adds a macro definition to a DWARF producer instance.

     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 macro is defined.  A line number of zero is used for macros that are
     defined before any source file is read.

     Argument name should point to a NUL-terminated string containing the name of the macro.  For function-like macros this parameter should also
     include parentheses and parameter names if any.

     Argument value should point to a NUL-terminated string containing the value of the macro.	If the macro doesn't have a value, argument value
     should be set to NULL.

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

EXAMPLE

     To record the fact that a macro named _STDIO_H_ was defined at line 20 of the current macro file, use:

	   Dwarf_P_Debug dbg;
	   Dwarf_Error de;

	   /* ... Assume 'dbg' refers to a DWARF producer instance... */
	   if (dwarf_def_macro(dbg, 20, "_STDIO_H_", NULL, &de) != DW_DLV_OK)
		   errx(EXIT_FAILURE, "dwarf_def_macro failed: %s",
		       dwarf_errmsg(-1));

ERRORS

     Function dwarf_def_macro() can fail with:

     [DW_DLE_ARGUMENT]	Either arguments dbg or name was NULL.

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