merror
merror(9F) Kernel Functions for Drivers merror(9F) NAME
merror - Send an M_ERROR message upstream SYNOPSIS
#include <sys/stream.h> #include <sys/strsun.h> void merror(queue_t *wq, mblk_t *mp, int error); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). PARAMETERS
wq Write queue associated with the read queue to send the M_ERROR on. mp Optionally, a STREAMS message to convert to an M_ERROR. error Error code to include in the M_ERROR message. DESCRIPTION
The merror() function constructs an M_ERROR message, and sends the resulting message upstream. If mp is NULL, merror() allocates a one-byte M_ERROR message. If mp is non-NULL, merror() attempts to convert the passed-in message to an M_ERROR. However, if the passed-in message has more than one reference (see dupmsg(9F)), or if it is of zero length, it is freed and a new message is allocated. If the allocation or conversion fails, merror() silently fails. Otherwise, the resulting one-byte data block is assigned the specified error code and sent upstream. RETURN VALUES
None. CONTEXT
This function can be called from user, kernel or interrupt context. NOTES
Callers must not hold any locks across an merror() that can be acquired as part of put(9E) processing. SEE ALSO
