Functions

This page explains roughly how the functions works.

rlibinput.h

inputstr()

Definition:

char *inputstr(char *askStr, int strSize, char *lengthError, int acceptNull, char *nullError);

Get a string (char *) input from the user.

Return value: A char pointer. ⚠️ Make sure to free() this return value.

askStr: A string used to prompt the user. Can be "" if you don't want to use it.

strSize: An int to set the max size of the input. (If 0, default to 1024)

lengthError: A string used to tell the user length of the input is invalid. (If "", it will default to : "The length of the input is invalid.")

acceptNull: A boolean (0 or 1) used to accept a empty input as a valid input. (0 = accept empty string, 1 = error if the string is empty, if neither 0 or 1, it will default to 0)

nullError: A string used to inform the user that the input is invalid if acceptNull = 1 and the input is empty. (If "", it will default to "The input is invalid.")

inputchar()

Definition:

char inputchar(char *askStr)

Get a char input from the user.

Return value: A char.
