int poptConfigFileToString FILE *    fp,
char **    argstrp,
int    flags
 

Parses an input configuration file and returns an string that is a command line. For use with popt. You must free the return value when done.

Given the file:

# this line is ignored
    #   this one too
aaa
  bbb
    ccc   
bla=bla

this_is   =   fdsafdas
     bad_line=        
  reall bad line  
  reall bad line  = again
5555=   55555   
  test = with lots of spaces

The result is:

--aaa --bbb --ccc --bla="bla" --this_is="fdsafdas" --5555="55555" --test="with lots of spaces"

Passing this to poptParseArgvString() yields an argv of:

'--aaa'
'--bbb' 
'--ccc' 
'--bla=bla' 
'--this_is=fdsafdas' 
'--5555=55555' 
'--test=with lots of spaces' 

Bug:
NULL is returned if file line is too long.

Silently ignores invalid lines.

Parameters:
fp  file handle to read
argstrp  return string of options (malloc'd)
flags  unused
Returns:
0 on success
