Comment (by SimonKing):
Here is the code for `system("uname")` (to be found in Singular/extra.cc):
{{{
#!C
/*==================== uname ==================================*/
if(strcmp(sys_cmd,"uname")==0)
{
res->rtyp=STRING_CMD;
res->data = omStrDup(S_UNAME);
return FALSE;
}
}}}
About `// ** s_internalDelete: cannot delete type sqrfree(493)`: According
to Hans, 493 is the token for the command `sqrfree`, which is ''not'' a
type but a command. Therefore deleting an object with 493's type is
impossible. He doesn't understand how that happens here.
`res->data` is a C string, and `STRING_CMD` is the token 495, which stands
for the type of a string (`char *`). Could Solares SPARC mistake 495 for
493??
