dlerror(3X) (C Programming Language Utilities) dlerror(3X)
NAME
dlerror - get diagnostic information
SYNOPSIS
cc [flag ...] file ... -ldl [library ...]
#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, will
result in NULL being returned.
SEE ALSO
dlerror(3X), dlopen(3X), dlsym(3X).
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.
