Need to create a memory leak

Hi. This might be a strange request, but does anyone have any idea on a simple shell script that would use more and more memory as it ran? Like a purposeful leak. I want to test the behaviour of an already running program when the machine runs out of memory. Thanks! (4 Replies)

NAME
pthread_attr_init, pthread_attr_destroy, pthread_attr_setstack, pthread_attr_getstack, pthread_attr_setguardsize, pthread_attr_getguardsize -- thread attribute operations SYNOPSIS
#include <pthread.h> int pthread_attr_init(pthread_attr_t *attr); int pthread_attr_destroy(pthread_attr_t *attr); int pthread_attr_setstack(pthread_attr_t *attr, void *stackaddr, size_t stacksize); int pthread_attr_getstack(const pthread_attr_t * restrict attr, void ** restrict stackaddr, size_t * restrict stacksize); int pthread_attr_setstacksize(pthread_attr_t *attr, size_t stacksize); int pthread_attr_getstacksize(const pthread_attr_t *attr, size_t *stacksize); int pthread_attr_setguardsize(pthread_attr_t *attr, size_t guardsize); int pthread_attr_getguardsize(const pthread_attr_t *attr, size_t *guardsize); int pthread_attr_setstackaddr(pthread_attr_t *attr, void *stackaddr); int pthread_attr_getstackaddr(const pthread_attr_t *attr, void **stackaddr); int pthread_attr_setdetachstate(pthread_attr_t *attr, int detachstate); int pthread_attr_getdetachstate(const pthread_attr_t *attr, int *detachstate); int pthread_attr_setinheritsched(pthread_attr_t *attr, int inheritsched); int pthread_attr_getinheritsched(const pthread_attr_t *attr, int *inheritsched); int pthread_attr_setschedparam(pthread_attr_t *attr, const struct sched_param *param); int pthread_attr_getschedparam(const pthread_attr_t *attr, struct sched_param *param); int pthread_attr_setschedpolicy(pthread_attr_t *attr, int policy); int pthread_attr_getschedpolicy(const pthread_attr_t *attr, int *policy); int pthread_attr_setscope(pthread_attr_t *attr, int contentionscope); int pthread_attr_getscope(const pthread_attr_t *attr, int *contentionscope); DESCRIPTION
Thread attributes are used to specify parameters to pthread_create(). One attribute object can be used in multiple calls to pthread_create(), with or without modifications between calls. The pthread_attr_init() function initializes attr with all the default thread attributes. The pthread_attr_destroy() function destroys attr. The pthread_attr_set*() functions set the attribute that corresponds to each function name. The pthread_attr_get*() functions copy the value of the attribute that corresponds to each function name to the location pointed to by the second function parameter. RETURN VALUES
If successful, these functions return 0. Otherwise, an error number is returned to indicate the error. ERRORS
The pthread_attr_init() function will fail if: [ENOMEM] Out of memory. The pthread_attr_destroy() function will fail if: [EINVAL] Invalid value for attr. SEE ALSO
pthread_attr_affinity_np(3), pthread_attr_get_np(3), pthread_create(3) STANDARDS
pthread_attr_init(), pthread_attr_destroy(), pthread_attr_setstacksize(), pthread_attr_getstacksize(), pthread_attr_setstackaddr(), pthread_attr_getstackaddr(), pthread_attr_setdetachstate(), and pthread_attr_getdetachstate() functions conform to ISO/IEC 9945-1:1996 (``POSIX.1'') The pthread_attr_setinheritsched(), pthread_attr_getinheritsched(), pthread_attr_setschedparam(), pthread_attr_getschedparam(), pthread_attr_setschedpolicy(), pthread_attr_getschedpolicy(), pthread_attr_setscope(), and pthread_attr_getscope() functions conform to Version 2 of the Single UNIX Specification (``SUSv2'') BSD
