If command is Template:cpp pointer, checks if host environment has a command processor and returns nonzero value only if it the command processor exists.
| command | - | character string identifying the command to be run in the command processor. If NULL pointer is given, command processor is checked for existence |
Template:returns
implementation-defined value. If command is Template:cpp returns nonzero value only if command processor exists.
