Expand description Represents an error encountered while using Hard.
sodium_malloc
returned an error when we tried to allocate a region of memory.
This is most likely to occur if there is not sufficient memory to allocate, but could occur
for other reasons. The associated value contains the value of the errno value, which is set
if sodium_malloc
fails.
sodium_mprotect_noaccess
returned an error.
This is most likely to occur if the platform we’re running on doesn’t have the mprotect
syscall (or its equivalent).
sodium_mprotect_readonly
returned an error.
This is most likely to occur if the platform we’re running on doesn’t have the mprotect
syscall (or its equivalent).
sodium_mprotect_readwrite
returned an error.
This is most likely to occur if the platform we’re running on doesn’t have the mprotect
syscall (or its equivalent).
sodium_init
returned an error.
