NAME pthread_attr_setstacksize - Changes the stacksize attribute of thread creation SYNOPSIS #include <pthread.h> int pthread_attr_setstacksize( pthread_attr_t *attr, long stacksize ); PARAMETERS attr Thread attributes object modified. stacksize New value for the stacksize attribute. The stacksize parameter specifies the minimum size (in bytes) of the stack needed for a thread. DESCRIPTION The pthread_attr_setstacksize() routine sets the minimum size (in bytes) of the stack needed for a thread created using the attributes object specified by the attr parameter. Use this routine to adjust the size of the writable area of the stack. The default value of the stacksize attribute is machine specific. A thread's stack is fixed at the time of thread creation. Only the main or initial thread can dynamically extend its stack. Most compilers do not check for stack overflow. Ensure that your thread stack is large enough for anything that you call from the thread. RETURN VALUES If the function fails, errno may be set to one of the following values: Return Error Description ___________________________________________________________ 0 Successful completion. -1 [EINVAL] The value specified by attr is invalid. -1 [EINVAL] The value specified by stacksize is invalid.
