return value description

[NEWPLAN]

Hi, where can we get the description of gdrcopy api in terms of its return value?

Hi @NEWPLAN can you be more specific? Which API in particular?

In general, all APIs follow the usual Unix convention, i.e. the integer return values are 0 (success) or >0 (error codes from errno.h). Except for gdr_open.
