It used to work in the past, for sure, and was used in some code over here...
Since it was an ad-hoc thing, the behavior might have changed -- I haven't
checked it lately.
To make the full disclosure, we reassign the entire __argv here from the linear
memory
array made up from new argv[] and argc (s_Argc is the original "argc" passed to
main()),
to make all command line to go into argv[0] for the purposes of "ps" output:
extern char** __argv;
extern int __argc;
char* cmdline;
char** x_argv;
size_t len;
int n;
for (len = 0, n = 0; n < argc; ++n)
len += strlen(argv[n]) + 1;
if (!(x_argv = (char**) malloc((s_Argc + 1) * sizeof(*x_argv) + len)))
return 0/*failure*/;
x_argv[0] = cmdline = (char*) x_argv + (s_Argc + 1) * sizeof(*x_argv);
memset(x_argv + 1, 0, s_Argc * sizeof(*x_argv));
for (n = 0; n < argc; ++n) {
if (n)
*cmdline++ = ' ';
len = strlen(argv[n]);
memcpy(cmdline, argv[n], len);
cmdline += len;
}
*cmdline = '\0';
__argv = x_argv;
__argc = 1;
