posix_spawnattr_getpartid()

Retrieve the partition identifiers currently set in the posix_spawnattr_t object

Synopsis:

#include <posix_spawnattr.h>

int posix_spawnattr_getpartid(
       const posix_spawnattr_t *_Restrict attrp,
       int *num,
       partlist_info_t plist_info[]);

Arguments:

attrp
A spawn file attribute object.
num
The number for the pointer of the elements that the partitions lists can contain.
plist_info
The partitions list information elements.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The caller must provide the storage for the partlist_info_t functions to be returned. The num pointer is initialized by the caller with the number of partlist_info_t elements plist_info has space for.

Upon return, num will be set as follows:


Note:

The caller can distinguish partition Id types with the PART_TYPE() macro defined in <part.h>.

This function is a QNX Neutrino extension to posix_spawnattr_t().


Returns:

The process ID of the child process, or -1 if an error occurs (errno is set).

Errors:

EINVAL
If there are any parameter errors.
EOK
Success.

Classification:

QNX Neutrino RTS

Safety:
Cancellation point No
Interrupt handler Yes
Signal handler Yes
Thread Yes
