pthread_attr_setstacksize(3THR) sets the thread stack size.
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 Stacksfor more information.
Prototype: int pthread_attr_setstacksize(pthread_attr_t *tattr, size_t size);
#include <pthread.h> pthread_attr_t tattr; size_t 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.
pthread_attr_setstacksize() returns zero after completing successfully. Any other return value indicates that an error occurred. If the following condition occurs, the function fails and returns the corresponding value.
