| priv_popen, priv_pclose - process IO |
| #include <privman.h> |
| FILE *priv_popen(const char *command, const char * type, const char *user,); int priv_pclose(FILE *stream); |
| The priv_popen() function opens a process by creating a pipe, forking, and invoking the shell. The type argument may specify only reading or writing, not both. The resulting stream is correspondingly read-only or write-only. |
| The command argument is a pointer to a null-terminated string containing a shell command line. The command is bassed to /bin/sh using the -c flag; interpretation, if any, is performed by the shell. The mode argument is a pointer to a null-terminated string which must be either `r' for reading or `w' for writing. |
| See the man page for popen(3) for more details, as this method parallels popen(3). |
| The priv_pclose function waits for the associated process to terminate, and returns the exit status of the command as returned by wait4. |
| On success, a pointer to a valid stream is returned. On error, NULL is returned and errno is set appropriately. |
| The priv_pclose function returns -1 if wait4 returns an error, or some other error is detected. |
| See popen(3) and pclose(3) for more detail. In addition to the errors listed there, priv_popen may set errno to EPERM if the user is not listed in an ``run_as'' configuration directive, or if the ``allow_as'' configuration primitive is not set to true. See privman_conf(5) for more details. |
