c_link
check if symbol loaded with dynamic link
Syntax
c_link(routine_name) [test, ilib] = c_link(routine_name) test = c_link(routine_name,num)
Arguments
- routine_name
a character string
- num
number of the shared library where routine_name is searched (-1: default, last used)
- test
boolean, indicates if there is a shared library which contains
routine_name
.- ilib
a scalar, the number of the shared library which contains
routine_name
Description
c_link
is a boolean function which checks if the
routine routine_name
is currently linked. This function
returns a boolean value true or false. When used with two return values,
the function c_link
returns a boolean value in
test
and the number of the shared library which
contains routine_name
in ilib
(when
test
is true).
Examples (C code)
if haveacompiler() then chdir(TMPDIR) f1=['int ext1c(int *n, double *a, double *b, double *c)' '{int k;' ' for (k = 0; k < *n; ++k) ' ' c[k] = a[k] + b[k];' ' return(0);}']; mputl(f1, TMPDIR + '/fun1.c'); //creating the shared library (a gateway, a Makefile and a loader are //generated. ilib_for_link('ext1c','fun1.c',[],"c"); // load the shared library exec loader.sce; // show link link('show') [test, ilib] = c_link('ext1c') // check if 'ext1c' symbol is linked in scilab (it returns %T, ilib equals to 0) c_link('ext1c', -1) // check if 'ext1c' linked in scilab in current library (last used) (it returns %T) c_link('ext1c', 0) // check in library (id eqs 0) if 'ext1c' is linked (it returns %T) c_link('ext1c', 1) // 'ext1c' not in library with id = 1 (it returns %F) c_link('toto') // returns %F 'toto' not linked to scilab (it returns %F) end
