POSIX_SPAWNATTR_GETFLAGS(3C) Standard C Library Functions POSIX_SPAWNATTR_GETFLAGS(3C)

posix_spawnattr_getflags, posix_spawnattr_setflagsget and set spawn-flags attribute of spawn attributes object

Standard C Library (libc, -lc)

#include <spawn.h>

int
posix_spawnattr_getflags(const posix_spawnattr_t *restrict attr, short *restrict flags);

int
posix_spawnattr_setflags(posix_spawnattr_t *attr, short flags);

The () function obtains the value of the spawn-flags attribute from the attributes object referenced by attr.

The () function sets the spawn-flags attribute in an initialized attributes object referenced by attr.

The spawn-flags attribute is used to indicate which process attributes are to be changed in the new process image when invoking posix_spawn(3C) or posix_spawnp(3C). It is the bitwise inclusive-OR of zero or more of the following flags:

These flags are defined in <spawn.h>. The default value of this attribute is as if no flags were set.

Upon successful completion, posix_spawnattr_getflags() returns 0 and stores the value of the spawn-flags attribute of attr into the object referenced by the flags parameter. Otherwise, an error number is returned to indicate the error.

Upon successful completion, posix_spawnattr_setflags() returns 0. Otherwise, an error number is returned to indicate the error.

These functions may fail if:

The value specified by attr is invalid.

The posix_spawnattr_setflags() function may fail if:

The value of the attribute being set is not valid.

The posix_spawnattr_getflags() and posix_spawnattr_setflags() functions conform to IEEE Std 1003.1-2001 (“POSIX.1”).
