const PathName: AnsiString; |
args: ppchar |
):cInt; |
FpExecVPreplaces the currently running program with the program, specified in PathName. The executable in pathis searched in the path, if it isn't an absolute filename. It gives the program the options in args. This is a pointer to an array of pointers to null-terminated strings. The last pointer in this array should be nil. The current environment is passed to the program. On success, execvpdoes not return.
Extended error information is returned by the FpGetErrnofunction:
