len_trim

Definition

Return the trimmed length of a string object.

This generic interface extends the intrinsic Fortran len_trim function to support the fpx string type.

The returned value corresponds to the number of characters after removing trailing blanks.

If the string is not allocated, the returned value is zero.

Examples

Basic usage:

type(string) :: s
 
s = 'foo'
print *, len_trim(s)     ! 3
 
s = 'foo '
print *, len_trim(s)     ! 3

Unallocated strings:

type(string) :: s
 
print *, len_trim(s)     ! 0
