Definition at line 475 of file epr_core.c.

epr_log()

void epr_log	(	EPR_ELogLevel	log_level,
		const char *	log_message
	)

Logs a message with the given log level.

The function calls this API's log handler if it is not NULL and if the given log level is greater than or equal to the global log level.

Parameters

log_level	the log level (or message type) for the mesage
log_message	the mesage

Definition at line 199 of file epr_core.c.

epr_make_os_compatible_path()

void epr_make_os_compatible_path

(

char *

path

)

Adapts path description to operating system.

Parameters

path	the path to a file.

Definition at line 449 of file epr_core.c.

epr_open_file()

FILE* epr_open_file

(

char *

file_path

)

Opens a file to read.

Parameters

file_path

the path to the file.

Returns

the file handle or NULL if an error occured.

Definition at line 295 of file epr_core.c.

epr_param_to_value()

epr_uint epr_param_to_value	(	const char *	str,
		EPR_SPtrArray *	param_table
	)

Finds in the param_table the value corresponding to its name.

Parameters

str	the parameter name
param_table	the pointer to param_table

Returns

the value of the given name or (uint)-1 if an error occured.

Definition at line 424 of file epr_core.c.

epr_parse_value_count()

epr_uint epr_parse_value_count	(	EPR_SProductId *	product_id,
		const char *	count
	)

Converts the given string into a field length.

The string can represent a single integer value or a sequence of integer value and parameter references (names). Integers and value are expected to be separated by the asterisk character ('*'). E.g. the string "3 * 4 * num_pixels_across" is represents a valid field length as long as the parameter name 'num_pixels_across' is found in the given parameter table.

Parameters

count	the string to be converted
product_id	the Product identifier containing the values for the Product

Returns

the field length computed from the given string or (uint)-1 if an error occured.

Definition at line 373 of file epr_core.c.

epr_set_err()

void epr_set_err	(	EPR_EErrCode	err_code,
		const char *	err_message
	)

Sets the given error code and the associated error message and calls this API's error handler if it is not NULL.

Parameters

err_code	the error code
err_message	the error mesage

Definition at line 221 of file epr_core.c.

epr_str_to_data_type_id()

EPR_EDataTypeId epr_str_to_data_type_id

(

const char *

str

)

Converts the given string into a data type identifier.

Parameters

str	the string to be converted.

Returns

the data type identifier represented by the given string. If the string can not be converted the special value e_tid_unknown is returned.

Definition at line 58 of file epr_core.c.

epr_str_to_number()

int epr_str_to_number

(

const char *

str

)

Converts the given string into an int number.

Parameters

str	the string to be converted.

Returns

the int type number represented by the given string. If the string can not be converted, the value of 1 is returned.

Definition at line 328 of file epr_core.c.
