The stacksize attribute defines the size of the stack (in bytes) that the system will allocate. The size should not be less than the system-defined minimum stack size. See "About Stacks"for more information.
Prototype: int pthread_attr_setstacksize(pthread_attr_t *tattr, int size);
#include <pthread.h> pthread_attr_t tattr; int size; int ret; size = (PTHREAD_STACK_MIN + 0x4000); /* setting a new size */ ret = pthread_attr_setstacksize(&tattr, size);
PTHREAD_STACK_MIN is the amount of stack space required to start a thread. This does not take into consideration the threads routine requirements that are needed to execute application code.
Returns zero after completing successfully. Any other returned value indicates that an error occurred. If the following condition occurs, the function fails and returns the corresponding value.
