# uconvert\_size(3alleg4)

Number of bytes needed to store a string after conversion. Allegro game programming library.

## NAME

uconvert\_size - Number of bytes needed to store a string after conversion. Allegro game programming library.

## SYNOPSIS

**#include \<allegro.h\>**

**int uconvert\_size(const char \*s, int type, int newtype);**

## DESCRIPTION

Finds out how many bytes are required to store the specified string \`s' after a conversion from \`type' to \`newtype', including the mandatory zero terminator of the string. You can use U\_CURRENT for either \`type' or \`newtype' as a shortcut to represent whatever text encoding format is currently selected. Example:

```
   length = uconvert_size(old_string, U_CURRENT, U_UNICODE);
   new_string = malloc(length);
   ustrcpy(new_string, old_string);
```

## RETURN VALUE

Returns the number of bytes required to store the string after conversion.
