Process Control error constants

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_ECHILD` (int)	No child processes
`PCNTL_EFAULT` (int)	Bad address
`PCNTL_EINTR` (int)	Interrupted function call
`PCNTL_EINVAL` (int)	Invalid argument
`PCNTL_EIO` (int)	Input/output error
`PCNTL_EISDIR` (int)	Is a directory
`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.
