ulink
unlink/unload a dynamically linked shared object
Syntax
ulink(x) ulink()
Arguments
- x
a ID returned by
link
Description
see link
If you plan to use valgrind to profile
your module, you must first set the environment
variable PROFILE_SCILAB_DYNAMIC_LINK before
starting scilab:
# under bash shell: export PROFILE_SCILAB_DYNAMIC_LINK=1 export SCILAB_VALGRIND_OPT="--db-attach=no --show-below-main=yes --log-fd=2 --log-file=scilab.txt --num-callers=50 -v --trace-redir=yes --read-var-info=yes --trace-children=yes --show-reachable=yes --smc-check=all --child-silent-after-fork=no --leak-check=full --track-origins=yes" scilab -nwni -profile
This environment variable force Scilab not to release the
loaded dynamic libraries. This will
allow valgrind to perform its sum-up analysis.
Examples
cd TMPDIR f1=['#include <math.h>' 'void fooc(double c[],double a[],double *b,int *m,int *n)' '{' ' int i;' ' for ( i =0 ; i < (*m)*(*n) ; i++) ' ' c[i] = sin(a[i]) + *b; ' '}']; mputl(f1,'fooc.c'); ilib_for_link('fooc','fooc.c',[],"c"); exec loader.sce; link() // Will should fooc link("show") // Will should the value 0 ulink(0) // ulink fooc
