int

cmakepp_lang/types/int.cpp_is_int(return str2check)

Determines if a string can lexically be cast to an integer.

For our purposes an integer is any string whose only characters are taken from the numbers 0 through 9, optionally prefixed with a - sign. In particular, this means that strings like " 2" are not recognized as integers by this function (note the space in " 2").

Parameters:

return (desc) – The name to use for the variable holding the result.
str2check (str) – The string which may be an integer.

Returns:

return will be set to TRUE if str2check is an integer and FALSE otherwise.

Return type:

bool

Error Checking

cpp_is_int will ensure that the caller has provided exactly two arguments. If the caller has provided a different amount of arguments this function will raise an error.
