spawn argv argument   
In  QNX 6.4.1 the documentation for spawn() says:
"The value in argv[0] should represent the filename of the program being loaded, but can be NULL if no arguments are 
being passed."

In practice, on an x86 platform, if argv[0] is NULL the call always fails with EINVAL.  Presumably either the 
implementation or the documentation is incorrect.

RE: spawn argv argument   
Nevertheless, I'll answer your question. The docs are wrong. In Neutrino
6.5.0, the description of argv is:

A pointer to an argument vector. The value in argv[0] can't be NULL, and
should represent the filename of the program being loaded. The last
member of argv must be a NULL  pointer. The value of argv can't be NULL.
