dlerror(S-osr5)
dlerror --
get diagnostic information
Syntax
cc . . . -lc
#include <dlfcn.h>
char *dlerror(void);
Description
dlerror(S-osr5)
returns a null-terminated character string (with no trailing newline)
that describes the last error that occurred during dynamic linking
processing.
If no dynamic linking errors have occurred since the last
invocation of dlerror,
dlerror returns NULL.
Thus, invoking dlerror
a second time, immediately following a prior invocation, results in
NULL being returned.
Notes
The messages returned by dlerror
may reside in a static buffer that is overwritten on each call to
dlerror.
Application code should not write to this buffer.
Programs wishing to preserve an error message should make their
own copies of that message.
