string file_to_string ( FILE *  fp  ) 

Read stuff from a file and dump it into a string. This assumes the file holds character data only. Intended for testing...

Parameters:
fp Read from this file
Returns:
Returns a string which holds the character data.

Definition at line 625 of file util.cc.

FILE* get_temp_file ( char *  temp  ) 

Intended for testing, this may have other uses. The template should be the pathname of the temporary file ending in 'XXXXXX' (as for mkstemp) and will be modified.

Parameters:
temp Pathname, ending in 'XXXXXX'
Returns:
A FILE pointer opened for update.

Definition at line 610 of file util.cc.

char* get_tempfile_template ( char *  file_template  ) 

Build a template for a temporary file suitable for use with mkstemp. Look around for a reasonable place to put a temporary file. Check first the value of the TMPDIR env var. If that does not yield a path that's writable (as defined by access(..., W_OK|R_OK)) then look at P_tmpdir (as defined in stdio.h. If both come up empty, then use `./'.

This function allocates storage using new. The caller must delete the char array.

Parameters:
file_template A template suitable for use with mkstemp (so it has to have six extra chars at its end. This is combined with the path to some temporary directory (see above).
Returns:
A writable char[] that holds the fully qualified filename/template to use with mkstemp.

string path_to_filename ( string  path  ) 

Get the filename part from a path. This function can be used to return a string that has the directory components stripped from a path. This is useful when building error message strings.

If WIN32 is defined, use '\' as the path separator, otherwise use '/' as the path separator.

Returns:
A string containing only the filename given a path.

Definition at line 560 of file util.cc.

string prune_spaces ( const string &  name  ) 

Removed spaces from the front of a URL and also from the front of the CE. This function assumes that there are no holes in both the URL and the CE. It will remove leading space, but not other spaces.

Todo:
Is this still needed? This function may predate the switch from libwww to libcurl and the latter may not need to have spaces removed.
Parameters:
name The URL to process
Returns:
Returns a new string object that contains the pruned URL.
