Read an integer parameter from a configuration file
#include <photon/PxProto.h>
int PxConfigReadInt( const char *section,
const char *entry,
int dflt,
int *value );
int PxConfigReadIntCx( PxCfgContext_t *cx,
const char *section,
const char *entry,
int dflt,
int *value );
- cx
- PxConfigReadIntCx() 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, or if the entry value is not a valid
integer (see below).
- value
- A pointer to an int where the function stores the value it
reads.
phexlib
These functions read an integer parameter from a configuration file.
The value can be signed. The characters after the sign determine the base:
Character(s):
|
Base: |
0x or 0X
|
Hexadecimal |
0
|
Octal |
Other digits
|
Decimal |
PxConfigReadInt() reads from the currently open configuration file
opened by PxConfigOpen(), while
PxConfigReadIntCx() reads from the configuration file indicated by
cx.
Pt_TRUE if the required section/entry exists and the given
value is valid, otherwise Pt_FALSE.
