problem in understanding the programme

hi, i am feeling difficulty in understanding the code . how can i go throw library functions in arduino environment how can i go throug " GSM gsmAccess" library suggset me howw to check in arduino environment otherwise suggest me one environment for verifying all internal functions. just like keil software that used to develope the code,we can verify and we can see internal functions in that also by opening them like that please suggest me any environments that can help to undestand the code deeply....

The library code is available for you to view/edit from the libraries folders. Personally I use an external editor to do this as I find it more convenient.

could you please tell me that external editor.

Notepad++ is a useful one.

it is ok but there is any other efficient editor like keil

I'm sure Keil's would work, but they'll relieve you of some money for the privilege. You could use the editor in Eclipse.

basically in which platform we are developing the code for arduino means embedded c r java
