Default Find mates in a SAM file

I want to identify the actual pairs of reads in a SAM file that potentially has multiple alignments for the same given pair.

Is it sufficient to check whether two lines in the SAM file have same QNAME?

Do I have to check for POS (start) and PNEXT (start of mate) fields and make sure they are matching between two lines?

I am aware of the meaning of SAM flags to identify paired and mapped reads. Simply checking the flag, however, does not allow me to identify the actual pair.

Thanks in advance.
