# fn() getBamTypeChar
Return char identifying the type of the argument type.

Defined in | <seqan/bam_io.h>
Signature | `char getBamTypeChar<T>(); BamTypeChar<T>::VALUE`

## Template Parameters

`T` | The type to query for its type char.

## Detailed Description

### Remarks

Note that this function is defined for the `int16_t`, `uint16_t` etc. but not for the types `short`, `int` etc. An exception are 8-bit characters/char, where it is defined for `int8_t`, `uint8_t`, and `char` unless `char` is equal to one of the other two types. This is important when used in setTagValue etc. since BAM gives type chars for printable characters, signed 8-bit numbers and unsigned 8-bit numbers.

If `int8_t` and `uint8_t` are not identical to `char`, we can make this decision from the type, otherwise we cannot and we will give the integer types a higher precedence.

In your programs, this should not make any difference, only the written SAM/BAM will differ.
