Константи Опис
PCNTL_E2BIG (int) Argument list too long
PCNTL_EACCES (int) Permission denied
PCNTL_EAGAIN (int) Resource temporarily unavailable
PCNTL_ECAPMODE (int) The process attempted an operation not permitted in capability mode while running in capability mode.

PCNTL_ELIBBAD (int) Accessing a corrupted shared library.
PCNTL_ELOOP (int) Too many levels of symbolic links
PCNTL_EMFILE (int) Too many open files. Commonly caused by exceeding the RLIMIT_NOFILE resource limit. Can also be caused by exceeding the limit specified in /proc/sys/fs/nr_open.
PCNTL_ENAMETOOLONG (int) Filename too long
PCNTL_ENFILE (int) Too many open files in system. On Linux, this is probably a result of encountering the /proc/sys/fs/file-max limit.
PCNTL_ENOENT (int) No such file or directory. Typically, this error results when a specified pathname does not exist, or one of the components in the directory prefix of a pathname does not exist, or the specified pathname is a dangling symbolic link.
PCNTL_ENOEXEC (int) Exec format error
PCNTL_ENOMEM (int) Not enough space/cannot allocate memory
PCNTL_ENOSPC (int) No space left on device
