RTOS/TM4C1294NCPDT: Is there an NDK function to convert between IP address strings and ints?

Nick W

Tool/software: TI-RTOS

When configuring the NDK, it accepts IP addresses and netmasks as strings in dotted decimal notation, but it would be easier for me to store user-configured IPs in EEPROM as a 32-bit ints. Is there a function available to convert between the two notations?

Upon some digging through headers, I found half of what I'm looking for: IPN inet_addr(char* address) in ti/ndk/inc/nettools/inc/inet.h goes from dotted decimal -> 32-bit int. Is there the opposite in the NDK as well? Also, does the inet_addr function do any validation in case of a malformed IP address?

Hi Nick,

There is inet_pton and inet_aton. This is some validation in the inet_aton API. It's probably easiest for you to look at source in <ndk_install_dir>\packages\ti\ndk\nettools\inet\inetaddr.c to see what it is checking.
