Subject: Argument parsing with gcc compiled program
Date: Thu, 26 Nov 2015 20:08:12 +0000

For some reason when I compile a C program in gcc, double backslashes within quotes are stripped.
But if I compile with Visual Studio this does not happen.  I used a small
test program to demonstrate.

VS
c:\msvc2010_SP1\VC>a.exe -s something "something d\:\\hello"

Command-line arguments:
  argv[0]   a.exe
  argv[1]   -s
  argv[2]   something
  argv[3]   something d\:\\hello
CL: a.exe  -s something "something d\:\\hello"


GCC
$ ./a.exe -s something "something d\:\\hello"

Command-line arguments:
  argv[0]   ./a
  argv[1]   -s
  argv[2]   something
  argv[3]   something d\:\hello
CL: K:\sat-misc\src\sat-main\sat\src\wiz\a -s something "something d\:\hello"


Is there some compiler option or setting I'm unaware of?
Thanks,
Glenn

#include <Windows.h>
#include <stdio.h>

int main( int argc, // Number of strings in array argv
 char *argv[],      // Array of command-line argument strings
 char **envp )      // Array of environment variable strings
{
    int count;
   char *gcl;

    // Display each command-line argument.
    printf("   \nCommand-line arguments:\n" );
    for( count = 0; count < argc; count++ )
        printf( "  argv[%d]   %s\n", count, argv[count] );

 
    gcl = GetCommandLine();
    printf("CL: %s\n",gcl);
}
