 * The prot shall be either PROT_NONE or the bitwise-inclusive OR of 
 * one or more of the other flags in the following table, defined in the
 * <sys/mman.h> header.
 * PROT_READ Data can be read.
 * PROT_WRITE Data can be written.
 * PROT_EXEC Data can be executed.
 * PROT_NONE Data cannot be accessed. 
 * If an implementation cannot support the combination of access types
 * specified by prot, the call to mmap( ) shall fail.
 *
 * Test Step:
 * 1. mmap(), setting 'prot' as PROT_NONE;
 * 2. mmap(), setting 'prot' as PROT_READ | PROT_WRITE | PROT_EXEC
