I am not using yours as your code sends the three file sequentially, but the required output sends three columns in a row, one at a time. That's why I concatenate three lines into one.
Your code sends the files one after another.
If I treat the three items (temperature, light, humidity) as a single intact record, then your output seems different from the sample output format, whereas my way seems to be what is required, except the following problems:
1)The whole dataset is output all at once, instead of individual record (3 numbers in a row);
2)The whole dataset is output in the way of 1) 30 times in total (which is exactly the total record numbers), that's what should be fixed.
Not sure if I missed some of your points. Thanks.
Hello,

Hi,
I wanted to write a socket program in C, where I always want my socket connected to the server. i.e i shouldn't get disconnected once i get the response back from the server. I want to work in the connected mode, instead of disconnect and connect.

h5totxt
H5TOTXT(1) h5utils H5TOTXT(1)NAME
h5totxt - generate comma-delimited text from 2d slices of HDF5 files
SYNOPSIS
h5totxt [OPTION]... [HDF5FILE]...
DESCRIPTION
h5totxt is a utility to generate comma-delimited text (and similar formats) from one-, two-, or more-dimensional slices of numeric datasets
in HDF5 files. This way, the data can easily be imported into spreadsheets and similar programs for analysis and visualization.
HDF5 is a free, portable binary format and supporting library developed by the National Center for Supercomputing Applications at the Uni-
versity of Illinois in Urbana-Champaign. A single h5 file can contain multiple data sets; by default, h5totxt takes the first dataset, but
this can be changed via the -d option, or by using the syntax HDF5FILE:DATASET.
By default, the entire dataset is dumped to the output. in row-major order. For 3d datasets, this corresponds to a sequence of yz slices,
in order of increasing x, separated by blank lines. If -T is specified, outputs in the transposed (column-major) order instead
Often, however, you want only a one- or two-dimensional slice of multi-dimensional data. To do this, you specify coordinates in one or
more slice dimensions, via the -xyzt options.
The most basic usage is something like 'h5totxt foo.h5', which will output comma-delimited text to stdout from the data in foo.h5.
OPTIONS -h Display help on the command-line options and usage.
-V Print the version number and copyright info for h5totxt.
-v Verbose output.
-o file
Send text output to file rather than to stdout (the default).
-s sep Use the string sep to separate columns of the output rather than a comma (the default).
-x ix, -y iy, -z iz, -t it
This tells h5totxt to use a particular slice of a multi-dimensional dataset. e.g. -x causes a yz plane (of a 3d dataset) to be
used, at an x index of ix (where the indices run from zero to one less than the maximum index in that direction). Here, x/y/z cor-
respond to the first/second/third dimensions of the HDF5 dataset. The -t option specifies a slice in the last dimension, whichever
that might be. See also the -0 option to shift the origin of the x/y/z slice coordinates to the dataset center.
-0 Shift the origin of the x/y/z slice coordinates to the dataset center, so that e.g. -0 -x 0 (or more compactly -0x0) returns the
central x plane of the dataset instead of the edge x plane. (-t coordinates are not affected.)
-T Transpose the data (interchange the dimension ordering). By default, no transposition is done.
-. numdigits
Output numdigits digits after the decimal point (defaults to 16).
-d name
Use dataset name from the input files; otherwise, the first dataset from each file is used. Alternatively, use the syntax
HDF5FILE:DATASET, which allows you to specify a different dataset for each file. You can use the h5ls command (included with hdf5)
to find the names of datasets within a file.
