NAMEdwarf_get_fde_range —
retrieve range information from an FDE descriptor
LIBRARYDWARF Access Library (libdwarf, -ldwarf)SYNOPSIS#include <libdwarf.h>
int
DESCRIPTIONFunctiondwarf_get_fde_range () retrieves range and
offset information from a given FDE descriptor.
Argument fde should reference a valid DWARF FDE descriptor. Argument low_pc should point to a location that will be set to the lowest program counter address covered by the FDE descriptor. Argument func_len should point to a location that will hold the length in bytes of the address range covered by the FDE descriptor. Argument fde_bytes should point to a location that will be set to a pointer to the content of the FDE descriptor itself. Argument fde_byte_len should point to a location that will hold the length in bytes of the FDE descriptor itself. Argument cie_offset should point to a location that will be set to the offset, relative to the DWARF “.debug_frame” section, of the CIE descriptor associated with the given FDE descriptor. Argument cie_index should point to a location that will hold the index of the CIE descriptor associated with the FDE descriptor. The returned value is a zero-based index into the array of CIE descriptors returned by a prior call to functions dwarf_get_fde_list(3) or dwarf_get_fde_list_eh(3). Argument fde_offset should point to a location that will be set to the offset, relative to the DWARF “.debug_frame” section, of the FDE descriptor. If argument err is not NULL, it will be used to store error information in case of an error. RETURN VALUESFunctiondwarf_get_fde_range () returns
DW_DLV_OK when it succeeds. In case of an error, it
returns DW_DLV_ERROR and sets the argument
err.
