stdlib.h

Description

Standard C library function that executes commands.

C-SPY debug action

Notifies the C-SPY debugger that system has been called and then returns -1.

Default implementation

The system function available in the library returns 0 if a null pointer is passed to it to indicate that there is no command processor, otherwise it returns -1 to indicate failure. If this is not the functionality that you require, you can implement your own version. This does not require that you rebuild the library.
