DWARF_NEW_FDE(3)					   BSD Library Functions Manual 					  DWARF_NEW_FDE(3)

NAME

     dwarf_new_fde -- allocate a DWARF frame descriptor

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     Dwarf_P_Fde
     dwarf_new_fde(Dwarf_P_Debug dbg, Dwarf_Error *err);

DESCRIPTION

     Function dwarf_new_fde() allocates a new DWARF frame descriptor.

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

     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_new_fde() returns the newly created frame descriptor.  In case of an error, function dwarf_new_fde() returns
     DW_DLV_BADADDR and sets the argument err.

ERRORS

     Function dwarf_new_fde() 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.

NAME

     dwarf_fde_cfa_offset -- add a DW_CFA_offset frame instruction to a DWARF frame descriptor

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     Dwarf_P_Fde
     dwarf_fde_cfa_offset(Dwarf_P_Fde fde, Dwarf_Unsigned reg, Dwarf_Signed offset, Dwarf_Error *err);

DESCRIPTION

     Function dwarf_fde_cfa_offset() appends a DW_CFA_offset frame instruction to the frame descriptor referenced by argument fde.

     Argument fde should reference a frame descriptor allocated using dwarf_new_fde(3).

     Argument reg specifies the register operand for the frame instruction.

     Argument offset specifies the offset operand for the frame instruction.

     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_fde_cfa_offset() returns the frame descriptor given in argument fde.  In case of an error, function
     dwarf_fde_cfa_offset() returns DW_DLV_BADADDR and sets the argument err.

ERRORS

     Function dwarf_fde_cfa_offset() can fail with:

     [DW_DLE_ARGUMENT]	Argument fde was NULL.

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