Thank you for the reply.
Unfortunately this is not the case. Here is a standard version (no
curses):
------------------------------------------------------------------
#include <stdio.h>
#include <gsl/gsl_matrix.h>
int
main (void)
{
int i, j;
int c = 5000;
gsl_matrix * m[c];
printf("press any key to allocate matrices...");
getchar();
for (i = 0; i < c; i++)
m[i] = gsl_matrix_calloc (100, 100);
printf("press any key to free the memory ...");
getchar();
for (i = 0; i < c; i++)
gsl_matrix_free (m[i]);
printf("press any key to exit... ");
getchar();
return 0;
}
// compile with :
// gcc -L/usr/local/lib test.c -lgsl -lgslcblas -lm
------------------------------------------------------------------
Here how it looks in sequence of execution:
1.
Program output:
press any key to allocate matrices...
Top output:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
20361 pliz 16 0 3736 580 460 S 0 0.0 0:00.00 a.out
2.
Program output:
press any key to free the memory ...
Top outputs:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
20361 pliz 20 0 385m 382m 524 S 0 19.0 0:00.63 a.out
3.
Program output:
press any key to exit...
Top output:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
20361 pliz 18 0 385m 382m 536 S 0 19.0 0:00.64 a.out
As you can see it is 385m of memory not de-allocated - not simple
auxiliary structures.
