第十题
#include<stdio.h>
int main(int argc, char *argv[])
{
int i = 0;
char buff[100];
memset(buff,0,sizeof(buff));
strncpy(buff, argv[0], sizeof(buff));
memset(argv[0],0,strlen(buff));
strncpy(argv[0], "NewName", 7);
// Simulate a wait. Check the process
// name at this point.
for(;i<0xffffffff;i++);
return 0;
}
[解决办法]
main( int argc, char *argv[ ], char *envp[ ] )
argv
An array of null-terminated strings. It can be declared as an array of pointers to char (char *argv[ ] or wchar_t *argv[ ] for wmain) or as a pointer to pointers to char (char **argv or wchar_t **argv for wmain). The first string (argv[0]) is the program name, and each following string is an argument passed to the program from the command line. The last pointer (argv[argc]) is NULL.
