* Name: exec |
|
* |
|
* Description: |
|
* This is a convenience function that wraps load_ and exec_module into |
|
* one call. |
|
* |
|
* Input Parameter: |
|
* filename - Fulll path to the binary to be loaded |
|
* argv - Argument list |
|
* exports - Table of exported symbols |
|
* nexports - The number of symbols in exports |
|
* |
|
* Returned Value: |
|
* This is an end-user function, so it follows the normal convention: |
|
* Returns the PID of the exec'ed module. On failure, it.returns |
|
* -1 (ERROR) and sets errno appropriately. |
|
