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.

DWARF_ADD_FRAME_CIE(3)					   BSD Library Functions Manual 				    DWARF_ADD_FRAME_CIE(3)

NAME

     dwarf_add_frame_cie -- add a call frame common information entry to a DWARF producer instance

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     Dwarf_Unsigned
     dwarf_add_frame_cie(Dwarf_P_Debug dbg, char *augmenter, Dwarf_Small caf, Dwarf_Small daf, Dwarf_Small ra, Dwarf_Ptr initinst,
	 Dwarf_Unsigned initlen, Dwarf_Error *err);

DESCRIPTION

     Function dwarf_add_frame_cie() adds a DWARF call frame common information entry (CIE) to a producer instance.

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

     Argument augmenter should point to a NUL-terminated augmentation string for the common information entry.

     Argument caf specifies the code alignment factor.

     Argument daf specifies the data alignment factor.

     Argument ra specifies the column number used for the return address register.

     Argument initinst should point to a byte stream containing the initial instructions for the common information entry.

     Argument initlen should hold the length in bytes of the byte stream pointed to by argument initinst.

     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_frame_cie() returns the index value of the created common information entry.  In case of an error, function
     dwarf_add_frame_cie() returns DW_DLV_NOCOUNT and sets the argument err.

ERRORS

     Function dwarf_add_frame_cie() 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.
