Detailed Description

Atari file handling callbacks.

Most of this code was taken from windows/gui.c

Function Documentation

atari_basename()

static nserror atari_basename ( const char *  path, char **  str, size_t *  size  )

static

Get the basename of a file using GEMDOS path handling.

This gets the last element of a path and returns it.

Parameters

[in]	path	The path to extract the name from.
[in,out]	str	Pointer to string pointer if this is NULL enough storage will be allocated for the path element.
[in,out]	size	The size of the space available if str not NULL on input and set to the total output length on output.

Returns

NSERROR_OK and the complete path is written to str or error code on faliure.

Definition at line 75 of file file.c.

Here is the call graph for this function:

atari_mkdir_all()

static nserror atari_mkdir_all ( const char *  fname )

static

Ensure that all directory elements needed to store a filename exist.

Parameters

fname

The filename to ensure the path to exists.

Returns

NSERROR_OK on success or error code on failure.

Definition at line 229 of file file.c.

References NSERROR_NOT_DIRECTORY, NSERROR_NOT_FOUND, NSERROR_OK, and nsmkdir.

atari_mkpath()

static nserror atari_mkpath ( char **  str, size_t *  size, size_t  nelm, va_list  ap  )

static

Generate a GEMDOS path from one or more component elemnts.

If a string is allocated it must be freed by the caller.

Parameters

[in,out]	str	pointer to string pointer if this is NULL enough storage will be allocated for the complete path.
[in,out]	size	The size of the space available if str not NULL on input and if not NULL set to the total output length on output.
[in]	nelm	The number of elements.
[in]	ap	The elements of the path as string pointers.

Returns

NSERROR_OK and the complete path is written to str or error code on faliure.

Here is the call graph for this function:

atari_nsurl_to_path()

static nserror atari_nsurl_to_path ( struct nsurl *  url, char **  path_out  )

static

Create a path from a nsurl using GEMDOS file handling.

Parameters

[in]	url	The url to encode.
[out]	path_out	A string containing the result path which should be freed by the caller.

Returns

NSERROR_OK and the path is written to path or error code on faliure.

Todo:

Need to check returning the unaltered path in this case is correct

Here is the call graph for this function:

atari_path_to_nsurl()

static nserror atari_path_to_nsurl ( const char *  path, struct nsurl **  url_out  )

static

Create a nsurl from a path using GEMDOS file handling.

Perform the necessary operations on a path to generate a nsurl.

Parameters

[in]	path	The path to convert.
[out]	url_out	pointer to recive the nsurl, The returned url should be unreferenced by the caller.

Returns

NSERROR_OK and the url is placed in url or error code on faliure.
