GFS_PIO_WRITE(3)														  GFS_PIO_WRITE(3)

NAME

       gfs_pio_write - write to a file

SYNOPSIS

       #include <gfarm/gfarm.h>

       gfarm_error_t gfs_pio_write (GFS_File gf, const void * buffer, int size, int * np);

DESCRIPTION

       gfs_pio_write()	writes	up to size bytes to the file gf from the buffer starting at buffer.  It returns the number of bytes written to the
       address pointed by np.

RETURN VALUES

       GFARM_ERR_NO_ERROR
	      The function terminated successfully.

       GFARM_ERR_OPERATION_NOT_PERMITTED
	      gf does not specify a regular file.

       GFARM_ERR_BAD_FILE_DESCRIPTOR
	      The file descripter specified by gfp is not a valid or is not open for writing.

       GFARM_ERR_NO_SPACE
	      The file system node has no room to store data

       GFARM_ERR_NO_FILE_SYSTEM_NODE
	      There is no available file system node.

       GFARM_ERR_NO_MEMORY
	      Insufficient memory was available.

       Others An error except the above occurred.  The reason is shown by gfarm_error_string(3).

GFS_PIO_GETS(3) 														   GFS_PIO_GETS(3)

NAME

       gfs_pio_gets - read one line

SYNOPSIS

       #include <gfarm/gfarm.h>

       char *gfs_pio_gets (GFS_File f, char * s, size_t size);

DESCRIPTION

       gfs_pio_gets()  reads one line from the file specified by the parameter gf to the buffer specified by the parameter s.  You need to specify
       the size of the buffer by the parameter size.

       Unlike gfs_pio_getline(3), this function doesn't remove newline character at the end of the buffer. But if whole contents of the line  can-
       not  be	stored to the buffer due to its length, or if the file reaches the end without newline, there will be no newline at the end of the
       buffer. In any case, one '' character is appended to the end of the buffer.

       If the file reaches its end, the length of the string in the buffer becomes 0.

RETURN VALUES

       NULL   The function terminated successfully.

       GFARM_ERR_NO_MEMORY
	      Insufficient memory was available.

       Others An error except the above occurred.  The reason is shown by its pointed strings.
