Set the spawn-pgroup attribute of a spawn attributes object.
#include <posix_spawnattr.h> int posix_spawnattr_setpgroup( posix_spawnattr_t *attrp, pid_t pid);
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The posix_spawnattr_setpgroup() function sets the spawn-pgroup attribute in an initialized attributes object referenced by attr.
The spawn pid_p attribute represents the process group to be joined by the new process image in a spawn operation (if POSIX_SPAWN_SETPGROUP is set in the spawn-flags attribute). The default value of this attribute is zero.
Upon successful completion, posix_spawnattr_setpgroup()) returns zero; otherwise, an error number is returned to indicate the error (errno is set).
