To return values, you can set a global variable with the result, or use command substitution, or you can pass in the name of a variable to use as the result variable. The examples below describe these different mechanisms. document; this might then cause the program calling system to behave in a non-conforming manner or to terminate. If the argument is a null pointer, the system function returns nonzero only if a command processor is available. If the argument is not a null pointer, and the system function does return, it returns an implementation-defined value. The return value of the command is in the upper 8 bits of the return value.
The value returned is -1 on error, and the return status of the command otherwise.

Many system calls return 0 on success, but some can return nonzero values from a successful call. The details are described in the individual manual pages. In some cases, the programmer must define a feature test macro in order to obtain the declaration of a system call from the header file specified in the man page SYNOPSIS section.
