| pipe |
| Prototype: |
#include <unistd.h>
int pipe(fd[2]);
|
| General Description: |
Creates a pipe that points to itself. Each file descriptor in fd[] coincides with input (fd[0]) and output (fd[1]). If you write to fd[1], you can read the data on fd[0]. Used mostly with fork(). |
| Return Value: |
Zero of okay; -1 on error. |
| Parameters |
| fd |
An array of two integers to receive the new file descriptor values. |
| Possible Errors |
| EMFILE |
Too file descriptors already in use by current process. |
| ENFILE |
The system's file table is full. |
| EFAULT |
The process does not own the memory that fd points to (invalid memory reference). |
| Examples |
int fd[2];
pipe(fd); /* create pipe */
