Function Documentation
__extern caca_file_t* caca_file_open (char const *path, const char *mode) Create a caca file handle for a file. If the file is zipped, it is
decompressed on the fly.
If an error occurs, NULL is returned and errno is set accordingly:
o ENOSTS Function not implemented.
o EINVAL File not found or permission denied.
Parameters:
path The file path
mode The file open mode
Returns:
A file handle to path.
Referenced by caca_import_canvas_from_file().
__extern int caca_file_close (caca_file_t *fp) Close and destroy the resources associated with a caca file handle.
This function is a wrapper for fclose() or, if available, gzclose().
Parameters:
fp The file handle
Returns:
The return value of fclose() or gzclose().
Referenced by caca_import_canvas_from_file().
__extern uint64_t caca_file_tell (caca_file_t *fp) Return the file handle position, in bytes.
Parameters:
fp The file handle
Returns:
The current offset in the file handle.
__extern size_t caca_file_read (caca_file_t *fp, void *ptr, size_tsize) Read data from a file handle and copy them into the given buffer.
Parameters:
fp The file handle
ptr The destination buffer
size The number of bytes to read
Returns:
The number of bytes read
Referenced by caca_import_canvas_from_file().
__extern size_t caca_file_write (caca_file_t *fp, const void *ptr, size_tsize) Write the contents of the given buffer to the file handle.
Parameters:
fp The file handle
ptr The source buffer
size The number of bytes to write
Returns:
The number of bytes written
__extern char* caca_file_gets (caca_file_t *fp, char *s, intsize) Read one line of data from a file handle, up to one less than the given
number of bytes. A trailing zero is appended to the data.
Parameters:
fp The file handle
s The destination buffer
size The maximum number of bytes to read
Returns:
The number of bytes read, including the trailing zero
__extern int caca_file_eof (caca_file_t *fp) Return the end-of-file status of the file handle.
This function is a wrapper for feof() or, if available, gzeof().
Parameters:
fp The file handle
