POSIX functions</H1 ><DIV CLASS="PARTINTRO" ><A NAME="AEN23371" ></A ><P > This module contains an interface to those functions defined in the IEEE 1003.1 (POSIX.1) standards document which are not accessible through other means. POSIX.1 for example defined the open(), read(), write() and close() functions, too, which traditionally have been part of PHP3 for a long time. Some more system specific functions have not been available before, though, and this module tries to remedy this by providing easy access to these functions. </P ></DIV ><DIV CLASS="TOC" ><DL ><DT ><B >Table of Contents</B ></DT ><DT ><A HREF="function.posix-kill.html" >posix_kill</A > — Send a signal to a process</DT ><DT ><A HREF="function.posix-getpid.html" >posix_getpid</A > — Return the current process identifier</DT ><DT ><A HREF="function.posix-getppid.html" >posix_getppid</A > — Return the parent process identifier</DT ><DT ><A HREF="function.posix-getuid.html" >posix_getuid</A > — Return the real user ID of the current process </DT ><DT ><A HREF="function.posix-geteuid.html" >posix_geteuid</A > — Return the effective user ID of the current process </DT ><DT ><A HREF="function.posix-getgid.html" >posix_getgid</A > — Return the real group ID of the current process </DT ><DT ><A HREF="function.posix-getegid.html" >posix_getegid</A > — Return the effective group ID of the current process </DT ><DT ><A HREF="function.posix-setuid.html" >posix_setuid</A > — Set the effective UID of the current process </DT ><DT ><A HREF="function.posix-setgid.html" >posix_setgid</A > — Set the effective GID of the current process </DT ><DT ><A HREF="function.posix-getgroups.html" >posix_getgroups</A > — Return the group set of the current process </DT ><DT ><A HREF="function.posix-getlogin.html" >posix_getlogin</A > — Return login name</DT ><DT ><A HREF="function.posix-getpgrp.html" >posix_getpgrp</A > — Return the current process group identifier </DT ><DT ><A HREF="function.posix-setsid.html" >posix_setsid</A > — Make the current process a session leader</DT ><DT ><A HREF="function.posix-setpgid.html" >posix_setpgid</A > — set process group id for job control</DT ><DT ><A HREF="function.posix-getpgid.html" >posix_getpgid</A > — Get process group id for job control</DT ><DT ><A HREF="function.posix-getsid.html" >posix_getsid</A > — Get the current sid of the process</DT ><DT ><A HREF="function.posix-uname.html" >posix_uname</A > — Get system name</DT ><DT ><A HREF="function.posix-times.html" >posix_times</A > — Get process times</DT ><DT ><A HREF="function.posix-ctermid.html" >posix_ctermid</A > — Get path name of controlling terminal</DT ><DT ><A HREF="function.posix-ttyname.html" >posix_ttyname</A > — Determine terminal device name</DT ><DT ><A HREF="function.posix-isatty.html" >posix_isatty</A > — Determine if a file descriptor is an interactive terminal </DT ><DT ><A HREF="function.posix-getcwd.html" >posix_getcwd</A > — Pathname of current directory</DT ><DT ><A HREF="function.posix-mkfifo.html" >posix_mkfifo</A > — Create a fifo special file (a named pipe) </DT ><DT ><A HREF="function.posix-getgrnam.html" >posix_getgrnam</A > — Return info about a group by name</DT ><DT ><A HREF="function.posix-getgrgid.html" >posix_getgrgid</A > — Return info about a group by group id</DT ><DT ><A HREF="function.posix-getpwnam.html" >posix_getpwnam</A > — Return info about a user by username</DT ><DT ><A HREF="function.posix-getpwuid.html" >posix_getpwuid</A > — Return info about a user by user id</DT ><DT ><A HREF="function.posix-getrlimit.html" >posix_getrlimit</A > — Return info about system ressource limits</DT ></DL ></DIV ></DIV ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="function.zend-logo-guid.html" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="manual.html" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="function.posix-kill.html" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >zend_logo_guid</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="funcref.html" >Up</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >posix_kill</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
