 ### Network errors
 
-The convention of the network socket API is for functions to return negative error codes to indicate failure. On success, a function may return zero or a non-negative integer to indicate the size of a transaction. On failure, a function must return a negative integer, which is one of the error codes in the `nsapi_error_t` [enum](/docs/development/mbed-os-api-doxy/group__netsocket.html#gac21eb8156cf9af198349069cdc7afeba):

-When Mbed OS is running on a PSA Security Model compliant target, the Mbed implementation of PSA helps to protect cryptographic assets, credentials and critical code sections by providing an isolation between a [Secure Processing Environment (SPE)](/docs/development/introduction/glossary.html) and a [Non-Secure Processing Environment (NSPE)](/docs/development/introduction/glossary.html). The [Secure Partition Manager (SPM)](/docs/development/introduction/glossary.html), which uses the target's hardware features, manages the isolation. The SPM provides standardized [IPC](/docs/development/introduction/glossary.html) APIs that you can use regardless of system architecture (v8M, TEE on Cortex-A) or inside another chip.
