dlopen(3) Guardian Native C Library Calls Reference Manual
• Could not be opened for execution
• Is not a DLL or an unlicensed public SRL
or if an error occurred during the loading or adjustment of the file’s symbolic references. The
dlerror() or dlresultcode() function should be called immediately to determine the problem.
ERRORS
The dlopen( ) function does not set the errno variable. Error information is available through the
dlerror() or dlresultcode() function.
Unresolved symbols can cause dlopen( ) to generate warnings or errors, depending on the user-
specified option for treating unresolved symbols. Warnings and errors are reported to the home
terminal.
If the option saved in the object file specifies that unresolved symbols generate errors, dlopen( )
returns 0 (zero) without loading any libraries; otherwise, dlopen() returns a valid library handle.
In the case of an error, a summary message can be retrieved by a call to dlerror().
RELATED INFORMATION
Commands: eld(1), ld(1).
Functions: dlclose(3), dlerror(3), dlresultcode(3), dlsym(3).
