Function capstone_sys::cs_op_count

pub unsafe extern "C" fn cs_op_count(
    handle: csh, 
    insn: *const cs_insn, 
    op_type: c_uint
) -> c_int

Count the number of operands of a given type. Find the operand type in header file of corresponding architecture (arm.h for ARM, x86.h for X86, ...)

NOTE: this API is only valid when detail option is ON (which is OFF by default)

handle: handle returned by cs_open() insn: disassembled instruction structure received from cs_disasm() or cs_disasm_iter() op_type: Operand type to be found.

return: number of operands of given type op_type in instruction insn, or -1 on failure.
