Strings and arrays

Hello people,

My question is C langage use.

I'd like to define a list of strings and to compare this list with a string incoming from the UART in order to build a command line interpreter.
The string from the UART is saved in a buffer. Let's name it au8TextBuffer.

The problem is that I can't do a

switch (au8TextBuffer)
   case "abc": ...
   case "def": ...

because the compiler returns an error. The switch function seems to not point on arrays


I could declare the strings in an 3D array

U8 au8text[3][3] = {"abc","def","ghi"};

but how to point on this array ?

I've seen on the web a method with structures, but it doesn't work :

#define CMD_TBL_LEN (sizeof (cmd_tbl) / sizeof (cmd_tbl [0]))

enum
{
	CMDID_HELP,
	CMDID_SETVAR,

	CMDID_ENDLIST
};

struct u8CommandString {
  	unsigned char *u8String;
  	unsigned char u8Identifier;
};

static struct u8CommandString CommandTable[] =
{
    	{ "HELP",	CMDID_HELP},
    	{ "SV",	CMDID_SETVAR},
};

U8 Cmdid_Search (U8 *u8String)
{
	struct u8CommandString *ctp;

	for (ctp = CommandTable; ctp < &CommandTable[CMD_TBL_LEN]; ctp++)
  	{
  		if (strcmp (ctp->u8String, u8String) == 0)
  		{
  			UART_Printf("reussi !!!!!");
  			return (ctp->u8Identifier);
  		}
  	}

	return (CMDID_ENDLIST);
}

The 'if (strcmp (ctp->u8String, u8String) == 0)' never works. I've tried to monitor on hyperterminal the ctp->u8String, but it displays irrelevant characters...



Any suggestion or link to browse ?

Thanks
