Bug ID: 94141
Summary: man page for dl_iterate_phdr() does not mention
current-executable-first iteration pattern
Product: Documentation
Version: unspecified
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P1
Component: man-pages
Assignee: documentation_man-pages-ztI5WcYan/[email protected]
Reporter: [email protected]
Regression: No
When I was using dl_iterate_phdr(), I noticed that the currently running executable wasn't showing up by name. And the first object visited by the iteration was unnamed.
According to this Stack Overflow page, the first object will always be the current executable:

But I didn't find any mention of this behavior in the official documentation:

Resolution|--- |CODE_FIX--- Comment #1 from Michael Kerrisk <[email protected]> --- I added some text to the man page to note this:
The first object visited by callback is the main program. For
the main program, the dlpi_name field will be an empty string.
Closing this bug.
