π dpdmai_close(9) β bestie's guide to closing the control session π
okay so this is a page from the Kernel API Manual, and it's about dpdmai_close β literally the "we're done here, bye" function for a DPDMAI object's control session. short page, but every word slaps, so let's go π«Ά
β¨ NAME β¨
dpdmai_close β close the control session of the object. that's it, that's the whole vibe check π
β¨ SYNOPSIS β¨
int dpdmai_close (struct fsl_mc_io *mc_io , u32 cmd_flags , u16 token );
look at her. three args, one int coming back at you. iconic signature, no notes π
β¨ ARGUMENTS β¨
mc_ioβ pointer to the MC portal's I/O object. this is the door you're knocking on, bestie πͺcmd_flagsβ command flags; one or more of'MC_CMD_FLAG_'. pick your flags, love πΈtokenβ token of DPDMAI object. it's like the object's little name tag so the kernel knows exactly which one you mean π
β¨ DESCRIPTION β¨
so here's the tea π΅ β after this function gets called, no further operations are allowed on the object unless you open a brand new control session. like, the door is shut. locked. sealed. the way that it is SO final π
fr fr, no cap: close first, and if you wanna do stuff again you gotta go through dpdmai_open(9) like a polite little function. don't be out here trying to operate on a closed session, that's not the move π
β¨ RETURN β¨
ngl, the original page leaves this section totally empty β no return values listed, nothing, just vibes and silence π so that's exactly what we're passing along to you: nothing documented here, bestie. that's the whole section. periodt.
