Why does GCC only complain about an unsigned int argument being used with %i when -pedantic is given?

Does that help -Wformat-signedness controls whether warnings are raised when the argument type differs only in signedness from what's expected.
From the gcc(1) man page:

Why does a default argument for a lambda argument trigger a -pedantic" GCC warning?

wish help you to fix your issue Section 5.1.2 paragraph 5 specifically says that you can not have default values for the parameters.

warning: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'long unsigned int *' [-Wfor

it should still fix some issue I get warning: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'long unsigned int *' [-Wformat] for the code below
code :
unsigned long  buf[254];
snprintf(systemlogmsg, sizeof(systemlogmsg), "INFO: %lu ",  buf[0]);  // ok
int s = 0, i;
for (i=0; i< 254; i++)
  s+=snprintf(systemlogmsg+s, 
       sizeof(systemlogmsg)-s, "INFO: %lu ",  buf[i]);  // ok

When does argparse not complain about this missing argument?

To fix the issue you can do At a glance, the -s option is boolean - so its presence implies True and it requires no argument. So when you say python test.py crossval -n 1 -s True, the True gets parsed as being the schema argument since the -s switch doesn't require a value.
This much can in fact be gleaned from the usage string in the help text:
code :
usage: test.py crossval [-h] [-n SAMPLENUM] [-p] [-s] schema

To fix this issue The following code used to compile fine. I migrated the project to a new version and now the compiler is complaining about one of my sprintf arguments. Here is the warning: , Argument 12 is:
code :
AnalysisEvents[id][index].min,
AnalysisEvents[id][index].minute,

Why does coverity complain when using calloc with unsigned int


By : Abdel Ghani

I wish this helpful for you The error message suggests that Coverity thinks that calloc returns an int, which can happen if you haven't included stdlib.h (for calloc) in the older C. But this is not allowed in modern C (i.e., no implicit declarations allowed in C99 and above).
