Set the possible attribute flags that can be set when a process is spawned
#include <posix_spawnattr.h> int posix_spawnattr_setxflags( posix_spawnattr_t *attrp, uint32_t flags);
The posix_spawnattr_setxflags() function sets the extended spawn-flags attribute in an initialized attributes object referenced by attrp.
POSIX specifies posix_spawnattr_setflags() and posix_spawnattr_getflags() routines for the setting of predefined flags using a flags parameter, which is defined as a short type.
Any flag not defined in this list won't be able to be set, and therefore not cause any actions. The posix_spawnattr_setxflags() function is a QNX Neutrino extension to posix_spawnattr_t(). |
Upon successful completion, posix_spawnattr_setxflags() returns zero; otherwise, an error number is returned to indicate the error (errno is set).
