Removes a message block from a message.
mblk_t *
rmvb(mp, bp)
register mblk_t * mp;
register mblk_t * bp;
The rmvb utility removes the message block pointed to by the bp parameter from the message pointed to by the mp parameter, and then restores the linkage of the message blocks remaining in the message. The rmvb utility does not free the removed message block, but returns a pointer to the head of the resulting message. If the message block specified by the bp parameter is not contained in the message specified by the mp parameter, the rmvb utility returns a -1. If there are no message blocks in the resulting message, the rmvb utility returns a null pointer.
This utility is part of STREAMS Kernel Extensions.
