Confused about how can I handle several "Possible" exceptions in C++ -

-

i'm going in c++, such creating file. in function creates file, have set several exceptions possible failure. instance if file exists, if disk full, if access allowed, if file creation ends happily etc...now, when want catch them all, confused.

int file_create(std::string file_name) {...} // includes several exceptions @ various points  try{     file_create("/var/simple.txt"); } catch(...){    // should here have specific control on exception throw? }

i know ... catch-all, not if lets deeper investigation of exception thrown?

i compile based on c++011.

you either like:

try { //your code } catch(firstexception &e){} catch(secondexception &e){} ...

or if want catch exceptions defined you, can create custom baseexception , define others subclasses of one.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
