vrb_write_min(3)					      VRB Programmer's Manual						  vrb_write_min(3)

NAME
vrb_write_min - write data from a VRB LIBRARY
-lvrb SYNOPSIS
#include <vrb.h> size_t vrb_write_min(vrb_p vrb, int fd, size_t maxsize, size_t minsize); DESCRIPTION
vrb_write_min writes a minimum amount of data to a specified open file descriptor using write(2) from the specified virtual ring buffer until the specified maximum length has been written, the buffer is full, or an error is returned (including EAGAIN or EWOULDBLOCK for a non-blocking descriptor). If there is insufficient data in the buffer to write the minimum amount, then write(2) will not be called. ARGUMENTS
vrb_p vrb specifies which virtual ring buffer. int fd specifies the open file descriptor to write to size_t maxsize specifies the maximum length to write, or ~0 for unlimited. size_t minsize specifies the minimum length to write. RETURN VALUE
size_t If successful, the actual length of data written from the buffer is returned. If the minimum amount of data was not available to be writ- ten, 0 is returned. If an error occurs from write(2), the return value is ~0 and errno is set by write(2). ERRORS
If an error is returned, then errno will have one of the following values: 0 An end-of-file has occurred. Note that this is a different way of returning an end-of-file condition than write(2) uses. EINVAL An invalid virtual ring buffer pointer was specified. SEE ALSO
