# buffer\_put(3)

write binary data to buffer

## NAME

buffer\_put - write binary data to buffer

## SYNTAX

**#include \<libowfat/buffer.h\>**

int **buffer\_put**(buffer\* *b*,const char\* *x*,size\_t *len*);

## DESCRIPTION

buffer\_put writes *len* bytes from *x* to *b*.

The difference to buffer\_putalign is that, when there isn't enough space for new data, buffer\_put calls buffer\_flush before copying any data, while buffer\_putalign fills all available space with data before calling buffer\_flush.

## RETURN VALUE

buffer\_put returns 0 if everything was fine, -1 on error (setting errno).

## SEE ALSO

[buffer\_putalign(3)](/buffer_putalign/3.md), [buffer\_puts(3)](/buffer_puts/3.md), [buffer\_flush(3)](/buffer_flush/3.md), [buffer(3)](/buffer/3.md)
