This patch adds a typedef target_xfer_partial_ftype. When we change the signature of xfer_partial functions (for example, adding a new parameter), we don't have to modify all of their declarations. This patch also updates the type of parameters of target_xfer_partial from "void *" to "gdb_byte *". gdb: 2013-12-18 Yao Qi <yao@codesourcery.com> * target.h (target_xfer_partial_ftype): New typedef. (target_xfer_partial): Update declaration. * auxv.h (memory_xfer_auxv): Likewise. * ia64-hpux-nat.c (super_xfer_partial): Likewise. * ia64-linux-nat.c (super_xfer_partial): Likewise. * linux-nat.c (super_xfer_partial): Likewise. * procfs.c (procfs_xfer_partial): Likewise. * record-full.c (record_full_beneath_to_xfer_partial): (tmp_to_xfer_partial): Likewise. * sparc-nat.c (inf_ptrace_xfer_partial): Likewise. * target.c (default_xfer_partial): Likewise. (current_xfer_partial): Likewise. (target_xfer_partial): Change parameter type to 'gdb_byte *'.
