# Generates NDK API txt file used by Mainline modules. NDK APIs would have value

# "UND" in Ndx column and have suffix "@LIB_NAME" in Name column.

# For example, current line llvm-readelf output is:

# 1: 00000000     0     FUNC      GLOBAL  DEFAULT   UND   dlopen@LIBC

# After the parse function below "dlopen" would be write to the output file.
