NAME
dlerror - get diagnostic information SYNOPSIS
#include <dlfcn.h> char *dlerror(void); DESCRIPTION
The dlerror() function returns a null-terminated character string that describes the last error that occurred during dynamic linking pro- cessing. The returned string contains no trailing newline. If no dynamic linking errors have occurred since the last invocation of dler- ror(), dlerror() returns NULL. Thus, invoking dlerror() a second time, immediately following a prior invocation, results in NULL being returned. USAGE
The dlerror() function is one of a family of functions that give the user direct access to the dynamic linking facilities. These facilities are available to dynamically-linked processes only. See Linker and Libraries Guide. ATTRIBUTES

The messages returned by dlerror() can reside in a static buffer that is overwritten on each call to dlerror(). Application code should not write to this buffer. Programs wanting to preserve an error message should make their own copies of that message. SunOS 5.11 1 Mar 2004 dlerror(3C)
