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:
- • ENOSTS Function not implemented.
• EINVAL File not found or permission denied.
- Parameters:
- • ENOSTS Function not implemented.
- path The file path
mode The file open mode - Returns:
- A file handle to path.
__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().
__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_t size)
- 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
__extern size_t caca_file_write (caca_file_t * fp, const void * ptr, size_t size)
- 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, int size)
- 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
- Returns:
- 1 if EOF was reached, 0 otherwise
