bool | pathname_ok (const string &path, bool strict) |
Does the string name a potentailly valid pathname? Test the given pathname to verfiy that it is a valid name. We define this as: Contains only printable characters; and Is less then 256 characters. If strict is true, test that the pathname consists of only letters, digits, and underscore, dash and dot characters instead of the more general case where a pathname can be composed of any printable characters. | |
bool | size_ok (uint sz, uint nelem) |
sanitize the size of an array. Test for integer overflow when dynamically allocating an array. |

FILE* get_temp_file | ( | char * | temp | ) |
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.
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). |

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.
bool pathname_ok | ( | const string & | path, | |
bool | strict | |||
) |
path | The pathname to test | |
strict | Apply more restrictive tests (true by default) |
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.
name | The URL to process |
