NAME

       getumask - get file creation mask

SYNOPSIS

       #include <sys/types.h>
       #include <sys/stat.h>

       mode_t getumask(void);

DESCRIPTION

       This function returns the current file creation mask.  It is equivalent to
	      mode_t getumask(void) {
		   mode_t mask = umask(0);
		   umask(mask);
		   return mask;
	      }
       except that it is documented to be thread-safe (that is, shares a lock with the umask() library call).

NOTES

       This function is documented but not implemented yet in glibc 2.2.5.

NAME

       umask - set and get file creation mask

SYNOPSIS

       #include <sys/types.h>
       #include <sys/stat.h>

       mode_t umask(mode_t cmask);

DESCRIPTION

       The  umask() function sets the  process's file mode creation mask to cmask and returns the previous value of the mask. Only the access per-
       mission bits of cmask and the file mode creation mask are used. The mask is inherited by child processes. See Intro(2) for more information
       on masks.

RETURN VALUES

       The previous value of the file mode creation mask is returned.
