 Modified Files:
 	src/share/man/man3: CMSG_DATA.3
 
 Log Message:
 cmsg(3): Handle as many descriptors as the sender sends in example.
 
 Due to a quirk of alignment, sizing the control buffer for
 CMSG_SPACE(sizeof(int)) does not guarantee at most one file
 descriptor fits in the buffer -- so if there is a chance the sender
 may send more than one descriptor, the receiver has to loop over all
 of them to avoid leaks.
 
 Prompted by:
 
 PR lib/59054: cmsg(3) uses malloc(3) unnecessarily
