Description

Shell invokes the bash shell (/bin/sh), and feeds it the command Command (using the -c option). The function then waits for the command to complete, and then returns the exit status of the command, or 127 if it could not complete the FpFork or FpExecve calls.

Errors

Extended error information is returned by the FpGetErrno function:
