Read a string parameter from a configuration file
#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 );
- 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.
phexlib
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.
Pt_TRUE if the required section/entry exists, otherwise
Pt_FALSE.
