Description
The
system function passes the string pointed to by
string to the host environment to
be executed by a command processor in an
implementation-defined manner. A null pointer may be used
for string to inquire whether a command processor exists.
Returns
If the argument is a null pointer, the system function
returns nonzero only if a command processor is available.
If the argument is not a null pointer, the system
function returns an implementation-defined value.
Implementation Notes
|
There is no command processor.
|
|
If the argument is a null pointer, then zero is
returned to indicate that a command processor is not
available.
|
|
If the argument is not a null pointer, the system function returns -1, and errno is set to ENOSYS.
