Access RTX register information

Hi,
Is it possible to access the variable name if we have an RTX which is a reg
that corresponds to a variable declared by the user?
I have found the macro REG_USERVAR_P (RTX) in rtl.h which returns the
boolean "1 if RTX is a reg that corresponds to a variable declared by the
user." But I am unable to get a suitable macro to get the variable name the
reg corresponds to.
On dumping the rtl output using the command:
print_rtl_single(stdout, in_rtx);
I get output:
(reg/v:SI 68 [ c ])
where "c" was the variable name defined by me. How do I access "c" given
the rtx statement, "in_rtx"?
Thank you very much in advance.
