Typedef Documentation

◆ crm_exit_t

typedef enum crm_exit_e crm_exit_t

Enumeration Type Documentation

◆ crm_exit_e

enum crm_exit_e

Exit status codes for tools and daemons.

We want well-specified (i.e. OS-invariant) exit status codes for our daemons and applications so they can be relied on by callers. (Function return codes and errno's do not make good exit statuses.)

The only hard rule is that exit statuses must be between 0 and 255; all else is convention. Universally, 0 is success, and 1 is generic error (excluding OSes we don't support – for example, OpenVMS considers 1 success!).

For init scripts, the LSB gives meaning to 0-7, and sets aside 150-199 for application use. OCF adds 8-9 and 190-191.

sysexits.h was an attempt to give additional meanings, but never really caught on. It uses 0 and 64-78.

Bash reserves 2 ("incorrect builtin usage") and 126-255 (126 is "command found but not executable", 127 is "command not found", 128 + n is "interrupted by signal n").

tldp.org recommends 64-113 for application use.

We try to overlap with the above conventions when practical.

◆ ocf_exitcode

Exit status codes for resource agents.

◆ pcmk_exec_status

Definition at line 305 of file results.h.

◆ pcmk_rc_e

enum pcmk_rc_e

Return codes for Pacemaker API functions.

Any Pacemaker API function documented as returning a "standard Pacemaker return code" will return pcmk_rc_ok (0) on success, and one of this enumeration's other (negative) values or a (positive) system error number otherwise. The custom codes are at -1001 and lower, so that the caller may use -1 through -1000 for their own custom values if desired. While generally referred to as "errors", nonzero values simply indicate a result, which might or might not be an error depending on the calling context.
