Get the spawn-schedpolicy attribute of a spawn attributes object
#include <posix_spawnattr.h> int posix_spawnattr_getschedpolicy( const posix_spawnattr_t *_Restrict attrp, int *_Restrict policy_p);
The posix_spawnattr_getschedpolicy() function shall obtain the value of the spawn-policy_p attribute from the attributes object referenced by attrp.
The posix_spawnattr_getschedpolicy() and posix_spawnattr_setschedpolicy() functions are part of the Spawn and Process Scheduling options and don't need to be provided on all implementations.
Upon successful completion, posix_spawnattr_getschedpolicy() returns zero and stores the value of the spawn-policy_p attribute of attrp into the object referenced by the policy_p parameter; otherwise, an error number is returned to indicate the error (errno is set).
