15 The dlerror() function returns a null-terminated character string that
16 describes the last error that occurred during dynamic linking process‐
17 ing. The returned string contains no trailing newline. If no dynamic
18 linking errors have occurred since the last invocation of dlerror(),
19 dlerror() returns NULL. Thus, invoking dlerror() a second time, imme‐
20 diately following a prior invocation, results in NULL being returned.
21
23 The dlerror() function is one of a family of functions that give the
24 user direct access to the dynamic linking facilities. These facilities
25 are available to dynamically-linked processes only. See Linker and
26 Libraries Guide.

50 The messages returned by dlerror() can reside in a static buffer that
51 is overwritten on each call to dlerror(). Application code should not
52 write to this buffer. Programs wanting to preserve an error message
53 should make their own copies of that message.
