PxConfigReadString(), PxConfigReadStringCx()

Read a string parameter from a configuration file

Synopsis:

#include <photon/PxProto.h>

int PxConfigReadString( const char *section,
                        const char *entry,
                        const char *dflt,
                        char *value,
                        short maxlen );

int PxConfigReadStringCx( PxCfgContext_t *cx,
                          const char *section,
                          const char *entry,
                          const char *dflt,
                          char *value,
                          short maxlen );

Arguments:

cx: PxConfigReadStringCx() 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. The first (maxlen-1) characters of the default string are copied (with a '\0' terminator appended).
value: A buffer where the function stores the value it reads.
maxlen: The maximum length of value. PxConfigReadString() copies a maximum of (maxlen-1) characters (with a '\0' terminator appended) in the string into the buffer at address value.

Library:

phexlib

Description:

These functions read a string parameter from the specified section and entry of a configuration file.

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

Returns:

Pt_TRUE if the required section/entry exists, otherwise Pt_FALSE.

Classification:

Photon

Safety:
Interrupt handler	No
Signal handler	No
Thread	No
