DWARF_FIND_MACRO_VALUE_START(3) 			   BSD Library Functions Manual 			   DWARF_FIND_MACRO_VALUE_START(3)

NAME

     dwarf_find_macro_value_start -- return the address of the first byte of a macro value

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     char *
     dwarf_find_macro_value_start(char *macro_string);

DESCRIPTION

     Given a DWARF macro string, function dwarf_find_macro_value_start() returns a pointer to the first byte of the macro value part of the macro
     string.

     Argument macro_string should be a NUL-terminated string conforming to the macro format defined in the DWARF standard; see dwarf(4).

RETURN VALUES

     On success, function dwarf_find_macro_value_start() returns a pointer to the first byte of the macro value.  If the macro value part was not
     found, function dwarf_find_macro_value_start() returns a pointer to the NUL-byte terminating argument macro_string.

     Function dwarf_find_macro_value_start() returns NULL if argument macro_string was NULL.

DWARF_VENDOR_EXT(3)					   BSD Library Functions Manual 				       DWARF_VENDOR_EXT(3)

NAME

     dwarf_vendor_ext -- add vendor-specific macro information to a DWARF producer instance

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     int
     dwarf_vendor_ext(Dwarf_P_Debug dbg, Dwarf_Unsigned constant, char *string, Dwarf_Error *err);

DESCRIPTION

     Function dwarf_vendor_ext() adds a vendor-specific macro information entry 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 constant specifies a constant value for the macro information entry.

     Argument string point to a NUL-terminated string containing the string value for the macro information entry.

     If argument err is not NULL, it will be used to store error information in case of an error.

     The meaning of the arguments constant and string are not defined by the DWARF specification, but are instead governed by application and ven-
     dor conventions.

RETURN VALUES

     On success, function dwarf_vendor_ext() returns DW_DLV_OK.  In case of an error, function dwarf_vendor_ext() returns DW_DLV_ERROR and sets
     the argument err.

ERRORS

     Function dwarf_vendor_ext() can fail with:

     [DW_DLE_ARGUMENT]	Either arguments dbg or string was NULL.

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