PutValue

Syntax

void putValue(EnvVarName, int val); // form 1

void putValue(EnvVarName, float val); // form 2

void putValue(EnvVarName, char val[]); // form 3

void putValue(EnvVarName, byte val[]); // form 4

void putValue(EnvVarName, byte val[], long vSize); // form 5

void putValue(char name[], int val); // form 6

void putValue(char name[], float val); // form 7

void putValue(char name[], char val[]); // form 8

void putValue(char name[], byte val[]); // form 9

void putValue(char name[], byte val[], long vSize); // form 10

Function

Assigns the valuevalto the environment variable with identifierEnvVarName/name. Integers are assigned to discrete environment variables (form 1 and 6), floating point numbers are assigned to continuous environment variables (form 2 and 7). The contents of a character string is assigned to character string environment variables (form 3 and 8). For data byte environment variables (form 4, 5, 9 and 10) the bytes of the data buffer are copied into the environment variable.

Parameters

EnvVarName Environment variable name (form 1-5).Must exist in the database.

name

Environment variable name (form 6-10)

val

New value of environment variable (form 1, 2, 6, 7) or buffer with new data (form 3, 4, 5, 8, 9, 10) and for form 5 and 10 the number of bytes to be copied.

Return Values
