Public Methods
| Hp49FileRead (string name, LogLevel lvl = NONE)
|
Constructor must be supplied with a file name
Parameters:
| name | File name
|
| lvl | Log level
|
Checks to see if the file is a valid Hp49 file.
Returns: Error: SUCCESS, MINOR (not valid Hp49 File), MAJOR (unable
to physically read file).
Reimplemented from Hp49File.
| bool readNibble (unsigned char&)
|
Trying to read past the end of file will be considered as an
error, especially since the data size of a file can be known
before hand.
| bool readByte (unsigned char&)
|
Basically two calls to readNibble
| Error readNibbles (unsigned long& n, const int c_sz)
|
Reads nibbles from file to be recognized as a long integer.
Therefore the first read nibble is the least significant and
the last is the most significant.
Parameters:
| n | returned result of nibbles read
|
| c_sz | number of nibbles to read
|
| Error readBytes (string&, const int sz)
|
Reads straight from the file, byte by byte, and places it in
a string.
Parameters:
| str | returned result of bytes read
|
| sz | number of bytes to read
|
| Error readData (string& data, unsigned long size = HPF_DEFAULT_FILE_SIZE)
|
Reads specified number of bytes of data from Hp49 file. After file is
read, pointer wil not be reseted and will not go beyond end-of-file.
This helps to have multiple reads for large files.
Parameters:
| data | String to store data into
|
| size | Number of bytes to read. Default is all bytes
