what are the crt files.

[Sanjeev Mk]

hi,
On compiling a C program, i see it gets linked to crt*  files. I understand these are the c runtime files.

What functions do these files carry out and how do they work?

In several of my programs,i have not used string operations or print operations.But still many of them get loaded into memory,as confirmed by the .map file. How to prevent this from happening? Does this have anything to do with the c runtime files?

Please help.
Sanjeev.
