Subject: new framework to inhibit thread cancellation when needed
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=729cb49f52c825ac44f437e1ff0865d9f0b3626a;hp=729cb49f52c825ac44f437e1ff0865d9f0b3626a

new framework to inhibit thread cancellation when needed

with these small changes, libc functions which need to call functions
which are cancellation points, but which themselves must not be
cancellation points, can use the CANCELPT_INHIBIT and CANCELPT_RESUME
macros to temporarily inhibit all cancellation.
