bionic (3) hdf_set_valuef.3.gz

NAME

       hdf_set_valuef  - Set the value of a named node

SYNOPSIS

       #include <util/neo_hdf.h>

       NEOERR* hdf_set_valuef (HDF *hdf, const char *fmt, ...)
                               ATTRIBUTE_PRINTF(2,3);

ARGUMENTS

       hdf -> the pointer to the hdf dataset
       fmt -> the name=value printf(3) format string

DESCRIPTION

       hdf_set_valuef  is  a convenience function that wraps hdf_set_value.  Due to limitations of C, the fmt is
       in the format "name=value", where we will first format the entire string, and then break it at the  first
       (from  the  left) equal sign (=) and use the left portion as the name and the right portion as the value.
       This function is somewhat inefficient in that it first allocates the full name=value, and then  the  call
       to  hdf_set_value  duplicates  the  value  portion, and then we free the name=value.  Currently, we don't
       strip whitespace from the key or value.  In the future, this function might  work  more  like  reading  a
       single line of an HDF string or file, allowing for attributes and symlinks to be specified...  maybe.

RETURN VALUE

       None
