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 counterpart, then the interface is thread-safe, and the non-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() fdatasync() 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() getutsid() getutsline() getutspid() getutxid() getutxline() getw() getwc() getwchar() getwd() glob() globfree() iconv() iconv_close() iconv_open() initgroups() insque() ioctl() isastream() lckpwdf() lockf() lockf64() lseek() lseek64() mkstemp() msgrcv() msgsnd() msync() nanosleep() nftw() nftw2() open() opendir() openlog() pause() pclose() perror() pfmt() poll() popen() pread() printf() pselect() pthread_cond_timedwait() pthread_cond_wait() pthread_join() pthread_testcancel() putc() putc_unlocked() putchar() putchar_unlocked() putmsg() putpmsg() putpwent() puts() pututline() pututsline() pututxline() putw() putwc() putwchar() putws() pwrite() read() readdir() readdir_r() readv() recv() recvfrom() recvmsg() remove() remque() rename() rewind() rewinddir() scandir() scanf() seekdir() select() semop() send() sendmsg() sendto() sendfile() setbwent() setgrent() setpwent() setusershell() setutent() setutsent() setutxent() sigpause() sigsuspend() sigtimedwait() sigwait() sigwaitinfo() sleep() socket() socketpair() statvfsdev() strerror() syslog() system() t_accept() t_alloc() t_bind() t_close() t_connect() t_error() t_getinfo() t_getprotaddr() t_getstate() t_listen() t_look() t_open() t_optmgmt() t_rcv() t_rcvconnect() t_rcvdis() t_rcvrel() t_rcvudata() t_rcvuderr() t_snd() t_snddis() t_sndrel() t_sndudata() t_strerror() t_sync() t_unbind() tcdrain() tmpfile() tmpnam() ttyname() ttyname_r() ttyslot() ulckpwdf() undial() ungetc() ungetwc() unlink() updatebwdb() usleep() utmpname() vfprintf() vfscanf() vfwprintf() vpfmt() vprintf() vscanf() vwprintf() wait() wait3() waitid() waitpid() wordexp() wordfree() wprintf() write() writev() wscanf() NOTE: A cancellation point WILL NOT occur when a thread is executing in in a UNIX 2003 conformant application. Cancel Safe All the following interfaces are Cancel Safe: accept() bind() connect() dn_comp() dn_expand() endhostent() endnetent() endprotoent() endservent() get_resfield() gethostbyaddr() gethostbyname() gethostent() getmsg() getnetbyaddr() getnetbyname() getnetent() getpeername() getpmsg() getprotobyname() getprotobynumber() getprotoent() getservbyname() getservbyport() getservent() getsockname() getsockopt() herror() inet_addr() inet_lnaof() inet_makeaddr() inet_netof() inet_network() inet_ntoa() isastream() listen() msync() net_aton() net_ntoa() poll() putmsg() putpmsg() rcmd() recv() recvfrom() recvmsg() res_init() res_mkquery() res_query() res_search() res_send() rexec() rresvport() ruserok() sbrk() send() sendfile() sendmsg() sendto() set_resfield() sethostent() setnetent() setprotoent() setservent() setsockopt() shutdown() socket() socketpair() Async Signal Safe All the following interfaces are Async Signal Safe: _exit() accept() access() alarm() bind() cfgetispeed() cfgetospeed() cfsetispeed() cfsetospeed() chdir() chmod() chown() close() connect() creat() dup() dup2() execle() execve() fcntl() flock() fpathconf() fstat() getegid() geteuid() getgid() getgroups() getmsg() getpeername() getpgrp() getpid() getpmsg() getppid() getsockname() getsockopt() getuid() isastream() kill() link() listen() lseek() memset() mkdir() mkfifo() msync() net_aton() net_ntoa() open() pathconf() pause() pipe() poll() putmsg() putpmsg() raise() read() recv() recvfrom() recvmsg() rename() rmdir() send() sendfile() sendmsg() sendto() setgid() setpgid() setsid() setsockopt() setuid() shutdown() sigaction() sigaddset() sigdelset() sigemptyset() sigfillset() sigismember() signal() sigpending() sigprocmask() sigqueue() sigsuspend() sleep() socket() socketpair() stat() sysconf() tcdrain() tcflow() tcflush() tcgetattr() tcgetpgrp() tcsendbreak() tcsetattr() tcsetpgrp() time() times() umask() uname() unlink() utime() wait() waitpid() write() NOTE: is not Async Signal Safe in a UNIX 2003 conformant application.
