Return to buf.h CVS log

Up to [local] / src / usr.bin / rcs

Remove file mode argument from {cvs|rcs}_buf_write_stmp().  We
always set the temporary file to mode 600, which is already done
by mkstemp().

OK joris@ and xsa@ over a month ago.

 * Buffer management
 * -----------------
 *
 * This code provides an API to generic memory buffer management.  All
 * operations are performed on a rcs_buf structure, which is kept opaque to the
 * API user in order to avoid corruption of the fields and make sure that only
 * the internals can modify the fields.
 *
 * The first step is to allocate a new buffer using the rcs_buf_create()
 * function, which returns a pointer to a new buffer.
