dlerror(S)


dlerror -- get diagnostic information

Synopsis

   #include <dlfcn.h>
   

char *dlerror(void);

Description

dlerror 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.

References

dlclose(S), dlopen(S), dlsym(S)

Notices

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.
