NAME

     dlerror -- get diagnostic information

SYNOPSIS

     #include <dlfcn.h>

     const char*
     dlerror(void);

DESCRIPTION

     dlerror() returns a null-terminated character string describing the last error that occurred on this thread during a call to dlopen(),
     dlopen_preflight(), dlsym(), or dlclose().  If no such error has occurred, dlerror() returns a null pointer.  At each call to dlerror(), the
     error indication is reset.  Thus in the case of two calls to dlerror(), where the second call follows the first immediately, the second call
     will always return a null pointer.

DESCRIPTION

       of the functions in the dlopen API since the last call to dlerror().  The returned string does not include a trailing newline.

       dlerror() returns NULL if no errors have occurred since initialization or since it was last called.
