COHERENT system calls        Overview       COHERENT system calls




The  COHERENT  system  makes many  services  available  to the  C
programmer.  A  programmer can use  a COHERENT service  through a
system call.   COHERENT's libraries include  the following system
calls:

bbrrkk()     Change size of data area
cchhddiirr()   Change working directory
cchhmmoodd()   Change file protection modes
cchhoowwnn()   Change ownership of a file
cchhrroooott()  Change process's root directory
cclloossee()   Close a file
ccrreeaatt()   Create/truncate a file
