PxConfigReadDouble(), PxConfigReadDoubleCx()

Read a double-precision float parameter from a configuration file

Synopsis:

#include <photon/PxProto.h>

int PxConfigReadDouble( const char *section,
                     const char *entry,
                     double dflt,
                     double *value );

int PxConfigReadDoubleCx( PxCfgContext_t *cx,
                       const char *section,
                       const char *entry,
                       double dflt,
                       double *value );

Arguments:

cx

PxConfigReadDoubleCx() only. The configuration file handle for the file you want to read from. This handle is returned by PxConfigOpenCx().

section

The section to read a value from.
If section is NULL, the function reads the value from entry in the current section. If section is a valid section name, it becomes the current section.

entry

The entry to read the value from.

dflt

The default to store in value if the specified section or entry don't exist.

value

A pointer to a double where the function stores the value it reads.

Library:

phexlib

Description:

These functions read a double-precision float parameter from a configuration file.

PxConfigReadDouble() reads from the currently open configuration file opened by PxConfigOpen(), while PxConfigReadDoubleCx() reads from the configuration file indicated by cx.

Returns:

Pt_TRUE if the required section/entry exists and the given value is valid, otherwise Pt_FALSE.

Classification:

Photon
