decToInt32TrueError Subroutine

public pure subroutine decToInt32TrueError(input, output, error, startpos, endpos)

Parse the input string as a signed decimal integer string to an int32 value.

This subroutine ignores leading and trailing whitespaces.

Error codes:
0 - none
1 - empty strings
2 - invalid format
3 - underflow
4 - overflow
5 - Invalid argument endpos/startpos

Arguments

Type IntentOptional AttributesName
character(len=*), intent(in) :: input

A string to be parsed as a signed decimal integer string to an int32 value.

integer(kind=k_int32), intent(out) :: output

An int32 value of the input string if no error has occurred during parsing.

integer(kind=k_int32), intent(out) :: error

An int32 value of 0 on successful parse cases or a true error code on unsuccessful parse cases.

integer(kind=k_int32), intent(in), optional :: startpos

An int32 value of the position(inclusive) of where to start parsing.

integer(kind=k_int32), intent(in), optional :: endpos

An int32 value of the position(inclusive) of where to end parsing.
