* the lowlevel function for cpcmd
int __cpcmd(const char *cmd, char *response, int rlen, int *response_code);
* cpcmd is the in-kernel interface for issuing CP commands
* cmd: null-terminated command string, max 240 characters
* response: response buffer for VM's textual response
* rlen: size of the response buffer, cpcmd will not exceed this size
* but will cap the output, if its too large. Everything that
* did not fit into the buffer will be silently dropped
* response_code: return pointer for VM's error code
* return value: the size of the response. The caller can check if the buffer
* was large enough by comparing the return value and rlen
* NOTE: If the response buffer is not in real storage, cpcmd can sleep
int cpcmd(const char *cmd, char *response, int rlen, int *response_code);
