wm_strSwitch()

Legacy Open AT
1

ascii src[]="+CMGL: 1,“REC UNREAD”,"+919686447047",“09/11/17,11:35:43+22”\r\n";

r=wm_strSwitch(src,“REC UNREAD”,NULL);

returns r=0
Dear all i try use the above function but it not giving me the expected result it is always returning zero.
What is the wrong i am doing here?

Anothre example:

ascii src[100]={“what is your name”};
r=wm_strSwitch(src,“your”,NULL);

returns r=0

2

Am i going out of wavecom?

Please reply for any reason.

what is wm_strSwitch supposed to do?
the funtion doesn’t seem to exist in my environment?
(OS version 6.31)

4

This function wm_strSwitch is given in Basic Development guide for Open AT OS v3.13 under standard library APIs

5

ok, foud it… (wasn’t loooking good enough.)

wow. that functionality really seems broken.

might strstr() be an option for you?

ascii src[100]={"what is your name"};
	char * pch;
	pch = strstr(src,"your");
	TRACE ((1,"r=%d",pch));

it returns a pointer to the location in the string, and NULL if no match

Realy good option i will work with this

Thankyou Madouc

That’s from the really old days when there were separate “Basic” and “ADL” APIs.

Now, it is all in the one ADL User Guide - in the section titled, “String Processing Function Set” under “Basic Features”.

i did find it when browsing around in the wm_stdio.h

9

I am using Q24plus on OS version AT v03.12. So i am referring Basic guide 3.13

I am getting result as below

ascii src[100]={“what is your name”};
r=wm_strSwitch(src,“your”,NULL);

returns r=0

Is it right or wrong?

10

As Madouc told is function broken?

11

the function is not responding as discribed in the documentation.

so i conclude it is broken (OS 6.31, FW 7.4a)

If wm_strSwitch does not work as you expect, You had better write a small of piece code to implement similar wm_strSwitch by yourself. c string library and wavecom string utility are very limited and do not expect Wavecom to provide everything for OAT app developers. You may have a look at source code (Match function) at codeguru.com/cpp/cpp/string/ … .php/c2807 to see whether it is good for you. Although it was written in C++, I can rewrite it in C for you if it is useful for you.

Thanks yuantuh

I will make use of strstr()

Have you notified Wavecom?

I haven’t yet.
