Set the maximum stack size attribute in a spawn attributes object
#include <spawn.h> int posix_spawnattr_setstackmax( posix_spawnattr_t *attrp, uint32_t size);
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The posix_spawnattr_setstackmax() function sets the maximum stack size attribute in the given spawn attributes object. If you don't specify a maximum, the stack for the child's main thread will be the default, 512 KB. You must have already initialized the spawn attributes object by calling posix_spawnattr_init().
This setting takes effect only if the POSIX_SPAWN_SETSTACKMAX flag is set in the spawn attributes; to set this flag, call posix_spawnattr_setxflags().
To retrieve the value of this attribute, call posix_spawnattr_getstackmax().
For more information about spawn attributes, see the entry for posix_spawn().
