pmNoMem is a convenience method that may be used when malloc(3) or a related memory allocation service fails.
A standard message is emitted using pmNotifyErr(3) with where used as a message prefix and the failing allocation size is also reported.
If fatal is zero (and PM_RECOV_ERR is zero), pmNoMem returns (the allocation failure is assumed to be recoverable by the caller), else (and PM_FATAL_ERR is a good value to use in this case) exit(2) is called with an argument of 1.
exit(2), malloc(3), PMAPI(3) and pmNotifyErr(3).
The man page pmnomem(3) is an alias of pmNoMem(3).
