0 value may be used to obtain current top address of .bss section. |
Return values
If the system call succeeds and it was invoked with ebx set to 0 the return value is the current top of .bss section. Otherwise the return value is a pointer to the start of the new area.
If the system call fails the return value is -ENOMEM.
