I'm just getting into Borland C++ and I'd like to use the Streams
package they supply.  Unfortunately, I've got to leap into this and
try to get something big ported from perl right away, so I don't have
the luxury of a lot of time to mosey through the manuals.

I have an input file that looks like this:

HEADER
 FIELD		FIELD2		FIELD3	...	FIELDN
 -------------- --------------- -------         -------------
 DATA1		DATA2		DATA3		DATAN

And I don't know a priori how many fields there will be.  I can use
the ---- line as a format specifier, but to do this, I'd like to chop
off that leading space.

I tried this after opening the file as a ifstream called tmpin:

char *tmpLine;

tmpin.resetiosflags(ios::skipws); // I want to preserve WS
tmpin >> ignore(1, '\n') >> tmpLine;


I get the following errors:

1.  'resetiosflags' is not a member of 'ifstream' (I Know, but it's a
stream manipulator, shouldn't it be accessible?)

2.  Function 'ignore' should have a prototype in function 'main' (but
ignore is defined as a member function of istream -- why isn't it
being recognized as such?)


Does anyone have any example code that does something real in Borland
C++ with streams?
