vc_gencmd_until
SYNOPSIS
int vc_gencmd_until(const char *cmd, const char *error_string, int timeout);
FUNCTION
Sends the command repeatedly, until one of the following situations occurs:
The specified response string is found within the gencmd response.
The specified error string is found within the gencmd response.
The timeout is reached.
The timeout is a rough value, do not use it for precise timing.
RETURNS
0 if the requested response was detected.
1 if the error string is detected or the timeout is reached.
