c_link

check if symbol loaded with dynamic link

Calling Sequence

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)'

            '  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)
