setproctitle can be implemented on Linux too, following code

is adopted from sendmail:

static char **Argv = NULL;
static char *LastArgv = NULL;
            
static void
init_setproctitle(int argc, char *argv[], char *envp[])
{
        
        extern char **environ;
                        
        int i, envpsize;
        char **p;
        
        for (i = envpsize = 0; envp[i] != ((void *) 0); i++)
                envpsize += strlen(envp[i]) + 1;
        
        if ((p = (char **) malloc((i + 1) * sizeof (char *))) != ((void *) 0)) {
                environ = p;
                
                for (i = 0; envp[i] != ((void *) 0); i++) {
                        if ((environ[i] =
                             malloc(strlen(envp[i]) + 1)) != ((void *) 0))
                                strcpy(environ[i], envp[i]);
                }
                
                environ[i] = ((void *) 0);
        }  

        Argv = argv;
        
        for (i = 0; i < argc; i++) {
                if (!i || (LastArgv + 1 == argv[i]))
                        LastArgv = argv[i] + strlen(argv[i]);
        }
        
        for (i = 0; envp[i] != ((void *) 0); i++) {
                if ((LastArgv + 1) == envp[i])  
                        LastArgv = envp[i] + strlen(envp[i]);
        }
                
}              
                
void
setproctitle(char *fmt, ...)
{
        va_list msg;
        static char statbuf[8192];

        char *p;
        int i, maxlen = (LastArgv - Argv[0]) - 2;
        
        va_start((msg), fmt);
        
        memset(statbuf, 0, sizeof (statbuf));
        vsnprintf(statbuf, sizeof (statbuf), fmt, msg);
        va_end(msg);
        
        i = strlen(statbuf);
        snprintf(Argv[0], maxlen, "%s", statbuf);
        p = &Argv[0][i];
        
        while (p < LastArgv)
                *p++ = '\0';
        Argv[1] = ((void *) 0);
