int _pclose(FILE * stream); 

Description 

Waits for piped command to complete. 

_pclose closes a pipe stream created by a previous call to _popen, and then waits for the associated child command to complete. 

Return Value 

On success, _pclose returns the termination status of the child command. This is the same value as the termination status returned by cwait, except that the high and low order bytes of the low word are swapped.  

On error, it returns -1.
