NAME
thread_safety - list of libc, libpthread and libgen interfaces that are: Not Thread-Safe, Cancellation Points,
Cancel Safe, Async Signal Safe, or Async Cancel Safe
DESCRIPTION
Refer to this manpage when writing thread-safe applications using libc, libpthread and libgen interfaces.
This manpage gives the list of libc, libpthread and libgen interfaces that are: Not Thread-Safe, Cancellation
Points, Cancel Safe, Async Signal Safe, or Async Cancel Safe.
Interfaces That Are Not Thread-Safe
All the interfaces are thread-safe except:
bgets() bufsplit() copylist()
dbmclose() dbminit() delete()
endmntent() fattach() fdetach()
fetch() firstkey() getc_unlocked()
getchar_unlocked() getcontext() getopt()
inet_ntop() inet_pton() isastream()
makecontext() memcntl() nextkey()
putc_unlocked() putchar_unlocked() setcontext()
setmntent() store() strord()
strtold() system() swapcontext()
NOTE: If an interface has a _r counterpart, then the _r interface is thread-safe, and the non-
_r is not
thread-safe.
Cancellation Points
Cancellation Points can occur when a thread is executing in the following interfaces:
_pututline() accept() aio_suspend()
bgets() bwtmpname() catclose()
catgets() catopen() close()
closedir() closelog() confstr()
connect() copylist() creat()
ctermid() cuserid() dbm_close()
dbm_delete() dbm_fetch() dbm_firstkey()
dbm_nextkey() dbm_open() dbm_store()
devnm() dial() endbwent()
endgrent() endpwent() endusershell()
endutent() endutsent() endutxent()
fclose() fcntl() fdopen()
fflush() fgetc() fgetpos()
fgetpwent() fgets() fgetwc()
fgetws() flock() fopen()
fprintf() fputc() fputs()
fputwc() fputws() fread()
freopen() fscanf() fseek()
fseeko() fsetpos() fstatvfsdev()
fsync() ftell() ftello()
ftw() fwprintf() fwrite()
fwscanf() getbwent() getc()
getc_unlocked() getchar() getchar_unlocked()
getcwd() getdate() getgrent()
getgrgid() getgrgid_r() getgrnam()
getgrnam_r() getlogin() getlogin_r()
getmsg() getpmsg() getpwent()
getpwnam() getpwnam_r() getpwuid()
getpwuid_r() gets() gettxt()
getusershell() getutent() getutid()
getutline() getutxent() getutsent()
