ap_os_dso_sym — return the address of a symbol
void *ap_os_dso_sym(void *handle, const char *symname)
Returns the address of symname
in the dynamic
shared object referred to by handle
. If the
platform mangles symbols in some way (for example, by prepending an
underscore), this function does the same mangling before lookup.
Returns NULL
if symname
cannot
be found or an error occurs.
