pthread_attr_setstacksize(3thr)pthread_attr_setstacksize(3thr)Namepthread_attr_setstacksize - Changes the stacksize attribute of thread
creation.
Syntax
#include <pthread.h>
int pthread_attr_setstacksize (attr, stacksize)
pthread_attr_t *attr;
int stacksize;
Arguments
attr Thread attributes object modified.
stacksize
New value for the stacksize attribute. The stacksize argument
specifies the minimum size (in bytes) of stack needed for a
thread.
Description
This routine sets the minimum size (in bytes) of the stack needed for a
thread created using the attributes object specified by the attr argu‐
ment. Use this routine to adjust the size of the writeable area of the
stack.
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 an error condition occurs, this routine returns -1 and sets errno to
the corresponding error value. Possible return values are as follows.
Return Error Description
0 Successful comple‐
tion.
-1 [EINVAL] The value specified
by attr is invalid.
