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. SEE ALSO

DWARF_UNDEF_MACRO(3)					   BSD Library Functions Manual 				      DWARF_UNDEF_MACRO(3)

NAME
dwarf_undef_macro -- record the removal of a macro definition LIBRARY
DWARF Access Library (libdwarf, -ldwarf) SYNOPSIS
#include <libdwarf.h> int dwarf_undef_macro(Dwarf_P_Debug dbg, Dwarf_Unsigned lineno, char *name, Dwarf_Error *err); DESCRIPTION
Function dwarf_undef_macro() records the removal of a macro definition in 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 definition was removed. A value of zero indicates that the macro definition was removed before any source files were read. Argument name should point to a NUL-terminated string containing the name of the macro. 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_undef_macro() returns DW_DLV_OK. In case of an error, function dwarf_undef_macro() returns DW_DLV_ERROR and sets the argument err. EXAMPLE
To record the fact that the macro named _STDIO_H_ was removed at line 220 of the current macro file, use: Dwarf_P_Debug dbg; Dwarf_Error de; /* ... Assume 'dbg' refers to a DWARF producer instance... */ if (dwarf_undef_macro(dbg, 220, "_STDIO_H_", &de) != DW_DLV_OK) errx(EXIT_FAILURE, "dwarf_def_macro failed: %s", dwarf_errmsg(-1)); ERRORS
Function dwarf_undef_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. SEE ALSO
