pSOSystem System Calls - Read

B Error Codes
This appendix is a collection of tables of pSOSystem error codes, intended to help
you identify which system call returned a specific error code. Each table lists the
codes belonging to a single pSOSystem component (i.e., pSOS+, pHILE+, etc.) The
table entry for each code includes a hexadecimal number, a brief description (including
the error mnemonic), and a list of the system calls that can return the error.
pSOSystem components return error codes in two ways:
■ pSOS+ and pHILE+ return error codes as function return values.
■ pREPC+, pNA+, and pRPC+ load the error code into an internal variable that
can be read through the macro errno(). If the return value of a pREPC+,
pNA+, or pRPC+ system call indicates an error, your application should examine
the errno variable to determine the cause of the error. See the description of
errno() on page 3-27 for more information.
Table B-1 lists the error code ranges of pSOSystem components, libraries, and drivers.
Error code values are in hexadecimal notation, with a space inserted every byte
for readability.
