If your file isn't too large (too large to fit in memory, pretty slow to read/write) you can circumvent any low level actions like seek and just read your file completely, change. On python 2, the return value is none; What this means is that when you use a std::basic_fstream, which by default uses a std::basic_filebuf, the single file position is moved by both seekp() and seekg(); So, if you want to read the whole file but skip the first 20 bytes, open the file, seek(20). Every individual seek, scan, lookup, or update on the specified index by one query execution is counted as a use of that index and increments the corresponding counter in this.
The return value of seek is not anything read from the file. File.seek(offset[, whence]) set the fileās current position, like stdioās fseek(). A seek() operation moves that pointer to some other part of the file so you can read or write at that place. Seek bar increase height [duplicate] ask question asked 12 years, 2 months ago. When sql server does a seek it knows where in the index that the data is going to be, so it loads up the index from disk, goes directly to the part of the index that.

On python 3, the return value is a number representing the new absolute position in the file,. The count(*) over() window function will help you count the number of total. I actually used this logic for. Note, the seek method is also called keyset pagination. The whence argument is optional and defaults to os.seek_set or 0 (absolute file positioning);.
The position returned by this extension will also work with binaryreader.seek as a start position when working with text files.
