CertStore_GetAvailableSpace function

  • Article

Header: #include <applibs/certstore.h>

Gets the remaining space that is available on the device for certificate storage, in bytes.

ssize_t CertStore_GetAvailableSpace(void);

Errors

Returns -1 if an error is encountered and sets errno to the error value.

  • EACCES: the operation isn't allowed because the CertStore capability isn't set in the application manifest.

  • EAGAIN: the OS certstore component isn't ready yet.

Any other errno may also be specified; such errors aren't deterministic and there's no guarantee that the same behavior will be retained through system updates.

Return value

Returns the available space for certificate storage in bytes, or -1 for failure, in which case errno is set to the error value.

Application manifest requirements

The application manifest must include the CertStore capability.
