How to store the name's of the running script? C-CodePudding

i don't want to encrypt my running program. So i need to get the name of this one.

Already i'm trying with argv[0] -> looks like "./main". I need to cut the "." from it. Tried with:

char exec_path[PATH_MAX];
for(int i=1; executableName[i]!='\0'; i  )
    {
        exec_path[i-1]=executableName[i];
    }
snprintf(exec_path, PATH_MAX, "%s/%s", name, exec_path);

but it returns too many error, and i think there is another nice solution. (maybe a lib?)

Basically, just by adding my argv[0] to the running path, i get this. U can see the problem.

EDIT:

Thanks to all answer, it worked with

memcpy(str, executableName 2, sizeof(executableName));
    snprintf(exec_path, PATH_MAX, "%s/%s", name, str);

CodePudding user response：

try this:

char* str = argv[0]   1;

CodePudding user response：

char *ans;
for (int i = strlen(argv[0]); i >=0; i--)
{
    if (argv[0][i] == '/')
    {
        ans = argv[0][i] 1;
        break;
    }    

}
