performs the architecture-dependent function specified by
number with the arguments specified by the
args pointer. args is a pointer
to a structure defining the actual arguments of the function. Symbolic
constants and argument structures for the architecture-dependent functions
can be found in the header file
system call should never be called directly by user programs. Instead, they
should access its functions using the architecture-dependent library.
See the manual pages for specific architecture-dependent function calls for information about their return values.
