hdf_get_valuevf(3) util/neo_hdf.h hdf_get_valuevf(3) NAME
hdf_get_valuevf - Return the value of a node in the data set SYNOPSIS
#include <util/neo_hdf.h> char* hdf_get_valuevf (HDF *hdf, const char *namefmt, va_list ap); ARGUMENTS
hdf -> the dataset node to start from namefmt -> the format string ap -> va_list of varargs DESCRIPTION
hdf_get_valuevf walks the data set pointed to by hdf via namefmt printf expanded with varargs ap, and returns the string value located there, or NULL if it doesn't exist. This differs from hdf_get_value in that there is no default value possible. RETURN VALUE

hdf_set_valuef(3) util/neo_hdf.h hdf_set_valuef(3) 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 sym- links to be specified... maybe. RETURN VALUE
