# filefn.h File Reference

## Classes
class | wxPathList
| The path list is a convenient way of storing a number of directories, and when presented with a filename without a directory, searching for an existing file in those directories. More...
## Defines
#define | wxCHANGE_UMASK(mask)
| Under Unix this macro changes the current process umask to the given value, unless it is equal to -1 in which case nothing is done, and restores it to the original value on scope exit.
## Typedefs
typedef off_t | wxFileOffset
| The type used to store and provide byte offsets or byte sizes for files or streams.
## Enumerations
enum | wxPosixPermissions { wxS_IRUSR = 00400, wxS_IWUSR = 00200, wxS_IXUSR = 00100, wxS_IRGRP = 00040, wxS_IWGRP = 00020, wxS_IXGRP = 00010, wxS_IROTH = 00004, wxS_IWOTH = 00002, wxS_IXOTH = 00001, wxPOSIX_USER_READ = wxS_IRUSR, wxPOSIX_USER_WRITE = wxS_IWUSR, wxPOSIX_USER_EXECUTE = wxS_IXUSR, wxPOSIX_GROUP_READ = wxS_IRGRP, wxPOSIX_GROUP_WRITE = wxS_IWGRP, wxPOSIX_GROUP_EXECUTE = wxS_IXGRP, wxPOSIX_OTHERS_READ = wxS_IROTH, wxPOSIX_OTHERS_WRITE = wxS_IWOTH, wxPOSIX_OTHERS_EXECUTE = wxS_IXOTH, wxS_DEFAULT, wxS_DIR_DEFAULT }
| File permission bit names. More...
enum | wxFileKind { wxFILE_KIND_UNKNOWN, wxFILE_KIND_DISK, wxFILE_KIND_TERMINAL, wxFILE_KIND_PIPE, wxFILE_KIND_UNKNOWN, wxFILE_KIND_DISK, wxFILE_KIND_TERMINAL, wxFILE_KIND_PIPE }
| File kind enumerations returned from wxGetFileKind(). More...
## Functions
bool | wxGetDiskSpace (const wxString &path, wxLongLong total=NULL, wxLongLong free=NULL)
| This function returns the total number of bytes and number of free bytes on the disk containing the directory path (it should exist).
wxString | wxGetOSDirectory ()
| Returns the Windows directory under Windows; other platforms return an empty string.
int | wxParseCommonDialogsFilter (const wxString &wildCard, wxArrayString &descriptions, wxArrayString &filters)
| Parses the wildCard, returning the number of filters.
void | wxDos2UnixFilename (wxChar *s)
| Converts a DOS to a Unix filename by replacing backslashes with forward slashes.
void | wxUnix2DosFilename (wxChar *s)
| Converts a Unix to a DOS filename by replacing forward slashes with backslashes.
bool | wxDirExists (const wxString &dirname)
| Returns true if dirname exists and is a directory.
void | wxSplitPath (const wxString &fullname, wxString *path, wxString *name, wxString *ext)
time_t | wxFileModificationTime (const wxString &filename)
| Returns time of last modification of given file.
bool | wxRenameFile (const wxString &file1, const wxString &file2, bool overwrite=true)
| Renames file1 to file2, returning true if successful.
bool | wxCopyFile (const wxString &file1, const wxString &file2, bool overwrite=true)
| Copies file1 to file2, returning true if successful.
bool | wxFileExists (const wxString &filename)
| Returns true if the file exists and is a plain file.
bool | wxMatchWild (const wxString &pattern, const wxString &text, bool dot_special)
| Returns true if the pattern matches the text; if dot_special is true, filenames beginning with a dot are not matched with wildcard characters.
wxString | wxGetWorkingDirectory (char *buf=NULL, int sz=1000)
wxString | wxPathOnly (const wxString &path)
| Returns the directory part of the filename.
bool | wxIsWild (const wxString &pattern)
| Returns true if the pattern contains wildcards.
bool | wxIsAbsolutePath (const wxString &filename)
| Returns true if the argument is an absolute filename, i.e.
wxString | wxGetCwd ()
| Returns a string containing the current (or working) directory.
bool | wxSetWorkingDirectory (const wxString &dir)
| Sets the current working directory, returning true if the operation succeeded.
bool | wxConcatFiles (const wxString &file1, const wxString &file2, const wxString &file3)
| Concatenates file1 and file2 to file3, returning true if successful.
bool | wxRemoveFile (const wxString &file)
| Removes file, returning true if successful.
bool | wxMkdir (const wxString &dir, int perm=wxS_DIR_DEFAULT)
| Makes the directory dir, returning true if successful.
bool | wxRmdir (const wxString &dir, int flags=0)
| Removes the directory dir, returning true if successful.
wxString | wxFindNextFile ()
| Returns the next file that matches the path passed to wxFindFirstFile().
wxString | wxFindFirstFile (const wxString &spec, int flags=0)
| This function does directory searching; returns the first file that matches the path spec, or the empty string.
wxFileKind | wxGetFileKind (int fd)
| Returns the type of an open file.
wxFileKind | wxGetFileKind (FILE *fp)
wxString | wxFileNameFromPath (const wxString &path)
char * | wxFileNameFromPath (char *path)
char * | wxGetTempFileName (const wxString &prefix, char *buf=NULL)
bool | wxGetTempFileName (const wxString &prefix, wxString &buf)
## Variables
const int | wxInvalidOffset = -1
| A special return value of many wxWidgets classes to indicate that an invalid offset was given.
