Package: manpages-dev
Version: 5.06-1
Severity: normal
Reading manual:
"""
int hsearch_r(ENTRY item, ACTION action, ENTRY **retval,
struct hsearch_data *htab);
Return Value:
hsearch_r() returns nonzero on success, and 0 on error.
Errors:
hsearch() and hsearch_r() can fail for the following reasons:
ENOMEM
action was ENTER, key was not found in the table, and there was no room in the
table to add a new entry.
ESRCH
action was FIND, and key was not found in the table.
"""
Well, there are few issues.
if hsearch_r returns 0 on error, how are the "reasons" indicated back to
the caller? The manpage doesn't say anything about it.
Also I would expect the EINVAL to be returned by hsearch_r when htab is
NULL. Or maybe state that behaviour is undefined if the htab is not a
result returned by previous hcreate_r call.
