Hi all,
I am having a project in Postgres where I need to modify some code in the parser section of the code base. During some analysis I came across a function called "base_yylex" which is called in the function yylex in the file parser.c. However, I was unable to find the definition of this function due to which I am stuck completely.
Looking forward to some help from experts.
Thanks in advance
Best regards,
Sayali

You need to read the flex manual... (hint: it's generated from scan.l)

Thanks a lot for these details Tom, I will checkout the scan.l file
