 int system(const char *string)

is a standard function defined in stdlib.h.

There is no requirement that it actually do anything, though.  If 
you want to know if the environment has a command-line processor 
capable of executing 'string', call system(NULL).  If it returns 
non-zero, the command-line processor is available.
