Hello,
I'm not really confident with C programming and it <string.h> library.
what i am trying to do is to extract a string between two string.
ex:
If I have "xxxxxxxSTARTmessageENDxxxxxxxxx" I need a function that will return "message" which is between "START" and "END"
Can anyone help me to write such a function or know any easier library easier than (string.h) please? Is (Better String library) good?
Thank you.
Make use of the strstr function.

hello,
OK, so i will do something like that:
I'll have B:"STARTmessageENDxxxxxxxxx"Code:A= "xxxxxxxSTARTmessageENDxxxxxxxxx" B = strstr (A,"START"), C = strstr (A, "END"),
C:"ENDxxxxxxxxx"
which function will allow me to do:
B = B - C then B = B - "START"
Thank you.
Notice that if you compute B + strlen("START") you will get a pointer to the first character of "messageENDxxxxxxxxx". Since you also have C, you can then copy over the characters in between (or simply set *C to '\0').

Sorry, I know it must be obvoius for you but i'm not sure what do you mean by "copy over the characters in between"? which function you are talking about?
Thank you.
It is probably good practice for you to write a loop to do that.
