Find data type of structure members of a C file

[vishnujs]

Hi,

I am completely new to perl.
what i want to do is to find if a specific data type is used inside the structure definitions in a C header file.

perl -ne 'print if /struct[^(].*{/ .. /}/' header.h | grep long

something like this will give an output provided the structure is defined like

struct tag {

in one single line
but i need to get the result even if the pattern is in multiple lines
like

struct tag 
{

I need two things infact, one is to find if a specific type is used in any of the structure definitions.
two is to replace a specific type with a new type in all structure definitions.




Thank you,
Regards
Vishnu

try adding the 's' option to the end of the regexp:

/struct[^(].*{/ .. /}/s

that way '.' can match a newline

Hay Kevin thanks for your reply.
i tried /s but it is not working. :-(

Well, that is my only suggestion.

@KevinADC
i think i will try concatenating multiple lines and searching in it. i might have to write some code in perl. lets see.
