[Gdb] breakpointing dynamically loaded library functions ??

[ankit thukral]

 hi,
     how does GDB breakpoints functions  like
 printf etc. which are a part of dynamically loaded
 library?
       actually, what i found out was that it follows
the same mechanism which it follows for breakpointing
normal functions (i.e., writing a SIGTRAP instruction
at the respective address).but what i have not been
able to figure out is that how does it maintain
consistency in library functions for different
processes that would be using these 'shared'
functions.
 
 thanks in advance,
 ankit.
