ReadMachOCommand()

template<typename T>

bool ReadMachOCommand ( DataExtractor & data, lldb::offset_t & offset, T & cmd )

static

Read a Mach-O load-command header (cmd + cmdsize) from data at offset into cmd, advancing offset by 8 bytes.

T may be llvm::MachO::load_command or any of its richer variants (thread_command, dylib_command, encryption_info_command, ...); only the leading cmd/cmdsize fields are touched by this read. Returns false on EOF or on a cmdsize smaller than sizeof(load_command), in which case callers should break out of their load-command loop to avoid spinning on malformed input.
